🇩🇪 D-AIHF, an Airbus A340-642 with Lufthansa (LH), was withdrawn from use (wfu) and ferried on April 2 to Teruel, Spain (TEV) for storage, although some accounts say it will be parted-out and scrapped. This frame was delivered to Lufthansa in February 2004.

🇧🇷 PR-YRF, an Airbus A320-251neo with Azul (AD), was wfu and ferried on April 1 to Coolidge, Ariz. (P08) for part-out and scrap. This frame was delivered new to the Brazilian airline in January 2017. After nine years, it is more valuable as parted components than as a complete aircraft.

Transportation Security Administration (TSA) screeners cleared 78,543,126 passengers last month, a modest 1.7 percent increase from March 2025 totals. This performance comes as TSA employees endured their second period of 45 plus days without pay since October. For the first quarter, passenger traffic across the approximately 440 airports in the TSA network was up 1.5 percent from 2025 with 208,633,153 passengers.

The president’s proposed budget for 2027 contains no provision for a civilian employee pay raise. This follows 2026, which saw a one percent increase, the smallest in five years. Historically, executive budget proposals from either party are viewed as aspirational, as Congress maintains the authority to override these recommendations regarding overall budget amounts and civilian compensation. This budgetary uncertainty directly affects TSA employees, many of whom have navigated significant financial challenges while maintaining operations for approximately 90 days without pay since October 1, 2025. EDITOR’S NOTE: We have a healthy contingent of federal employees who read Flightline, which is why this bit is included.

The president’s proposed budget (pg. 27) would also mandate that small airports enroll in the Screening Partnership Program (SPP). This program allows airports to use private contractors instead of federal screeners, while the TSA (which the document calls a “troubled federal agency” without further explanation) retains full oversight. Under SPP, TSA still sets all procedures, certifies personnel, and enforces compliance standards. The passenger experience and security requirements remain the same, with differences largely limited to staffing and uniforms. Apart from San Francisco (SFO) and Kansas City (MCI), the program is used at a limited number of U.S. airports, mostly in Montana and other rural areas. In nearly 25 years, no airport of even moderate size has attempted to switch from TSA to private screeners.

The president’s budget proposal also aims for deep cuts to the Essential Air Service (EAS), a U.S. government program established after the 1978 airline deregulation to ensure that small and rural communities maintain a minimal level of scheduled commercial flights. By providing federal subsidies to airlines, the program guarantees that these otherwise unprofitable locations remain connected to the national air transportation system through at least one major hub. EDITOR’S NOTE: Recent EAS routes include Sun Country Airlines’ (SY) rather dubious flight from Eau Claire, Wis. (EAU) to Fort Myers, Fla. (RSW), a route which ends for the 2026 season today.

Senator Tammy Duckworth (D-IL) is demanding that the TSA immediately rescind a policy implemented by former Department of Homeland Security (DHS) Secretary Kristi Noem that allows travelers to keep their shoes on during airport security screenings. The Senator cites a DHS Office of Inspector General report which found that full-body scanners cannot effectively scan shoes, creating a significant security vulnerability. Duckworth argues that maintaining this policy despite these findings violates federal law and recklessly increases the risk of a terrorist attack. The full letter is included below.

The Federal Aviation Administration (FAA) has proposed a $304,272 civil penalty against Southwest Airlines (WN) for allegedly violating drug and alcohol testing regulations. The FAA alleges that Southwest failed to conduct all of the required follow-up drug or alcohol testing for 11 employees, including pilots, flight attendants, and aircraft mechanics. The employees had previously tested positive for alcohol or drugs including marijuana, cocaine and amphetamines. During various periods between August 2021 and July 2024, the employees performed safety-sensitive functions when Southwest Airlines did not subject them to the required follow-up testing. Southwest Airlines has 30 days after receiving the FAA’s enforcement letter to respond to the agency.   

A new Phocuswright study finds that a majority of U.S. travelers are now using artificial intelligence as part of their trip planning and travel experience, marking the fastest behavioral shift in more than a decade. More than half of travelers have used AI for at least one trip, with adoption more than doubling since 2024 and spreading across all age groups, led by millennials and Gen Z. Usage is expanding beyond pre-trip research into real-time, in-destination support, where travelers rely on AI for navigation, recommendations, and itinerary management, with 95 percent rating it helpful. Despite the surge, travelers continue to verify information, with about half still clicking through to traditional sources, underscoring that AI is complementing rather than replacing existing travel planning tools. 

Scandinavian Airlines (SAS) has launched a review of its procedures after two separate incidents in just over a month in which flight attendants tested positive for alcohol while on duty, one at Stockholm Arlanda (ARN) in late February and another at Copenhagen (CPH) on March 26. In both cases, the crew members were removed from duty, with one reportedly detained, prompting the airline to reiterate its strict zero-tolerance policy on alcohol and drugs for safety-critical roles. SAS said it is taking the incidents seriously and will strengthen preventive measures, though it has not disclosed what disciplinary action the employees may face. 

The FAA officially banned simultaneous parallel landings at San Francisco on March 31, 2026, citing critical safety concerns regarding aircraft separation. The agency determined that San Francisco's parallel runways, which are spaced only 750 feet apart, no longer meet national safety standards for visual side-by-side approaches. This decision was further influenced by broader safety reviews following a series of near-miss incidents and a tragic 2025 collision involving an American Eagle flight. To mitigate these risks, the FAA now mandates staggered approaches, which has forced a significant reduction in the airport's arrival capacity from 54 flights per hour to 36 flights per hour, which is a one-third cut to operations. These operational constraints are expected to increase flight delays by approximately 25 percent, particularly as they coincide with a six-month runway repaving project scheduled through October 2026.

Following the integration with Alaska Air Group, Hawaiian Airlines (HA) pilots are now being required to comply with Alaska Airlines grooming standards, which prohibit beards. The change marks a notable shift for Hawaiian pilots, who had previously been allowed to wear neatly trimmed facial hair under their own company policies. The policy aligns with Alaska’s interpretation of safety and uniformity standards, including concerns around proper oxygen mask sealing, though it runs counter to a broader industry trend toward more relaxed grooming rules. The move has generated some internal friction, as it represents one of the more visible cultural changes resulting from the merger.

Ireland’s Ryanair flew 15.8 million passengers in March, a five percent bump from March 2025. The discounter was able to fill 93 percent of its available revenue seats during the month. For the last 12 months, Ryanair has flown 208.4 million passengers, with only six percent of its seats empty.

Wizz Air (W6) enjoyed an 8.4 percent uptick in March passenger traffic, with the Hungarian concern filling 90 percent of its revenue seats with 5,511,602 passengers. For the first quarter of 2026, Wizz’s passenger traffic is up just under eight percent to 15,781,505.

The Japan Airlines Group carried 3,629,166 passengers in February, including 3,003,493 on domestic routes and 625,673 on international services. Load factors came in at 87.5 percent domestically and 86.1 percent internationally.

The All Nippon Airways Group transported 4,190,372 passengers during the month, with 3,450,472 traveling within Japan and 739,900 on international routes. Load factors reached 81.1 percent for domestic operations and 85.5 percent for international services.

Let’s take a look at the present estimated value of the largest airline loyalty programs in the world. Now, you may recall Flightline 75 and a discussion on airline miles - “The Great Mileage Heist.” We noted that “while investors celebrate "record profits" at giants like Delta and United, the reality under the hood is that these carriers are increasingly acting as banks that happen to fly planes. For major legacy carriers, loyalty programs are no longer just marketing "perks"; they are the financial bedrock keeping the wings level. During the global downturn of the early 2020s, airlines survived by using these programs as collateral for billions in loans. Nearly all U.S. airlines lose money flying passengers.”

What is remarkable in this case is the sheer valuation of these loyalty programs. The value of United Airlines MileagePlus is nearly equivalent to the airline’s total market capitalization. Furthermore, American Airlines (AA) AAdvantage program is valued at nearly four times the worth of the airline itself, while the Southwest Airlines Rapid Rewards plan is worth approximately twice the value of the carrier Here are the Top 100 most valuable airline mileage programs as of 2026:

South Korean startup SUM Air (XU) has placed a firm order for eight ATR 72-600 turboprops, with options for four additional aircraft, as it builds out a regional network focused on underserved domestic markets. Deliveries are scheduled to begin in 2028, with the aircraft set to support short-haul operations linking mainland cities with island airports such as Ulleungdo, Baengnyeongdo, and Heuksando. The order, signed during the France–Korea Bilateral Economic Forum in Seoul, underscores the airline’s strategy to leverage turboprop economics and short-runway performance to expand connectivity across Korea’s fragmented geography, just weeks after launching operations with a leased ATR 72-600.

The Department of Transportation’s (DOT) Air Travel Consumer Report (ATCR) is a monthly publication designed to inform the public about the quality of service provided by U.S. airlines. The report aggregates key operational data, including on-time performance, flight cancellations, and mishandled baggage. Here are the full numbers for all of 2025, the most recent data released.

Following the lead of JetBlue Airways, United Airlines has increased its checked bag fees by $10 for most domestic flights. While some specific international or specialty routes have seen larger adjustments, the standard domestic increase moved the cost for a first checked bag to $40 for those who do not prepay, or $35 for those who pay at least 24 hours in advance.

This adjustment is primarily driven by the significant surge in jet fuel costs and increased labor contracts, which have pressured airline margins across the industry. By raising these ancillary fees, the carrier aims to maintain profitability while navigating the volatile energy market and sustained inflationary pressures.

Embraer reported a strong start to the year, delivering 44 aircraft during the first quarter of 2026. This total included 15 commercial jets and 29 executive jets, representing a 25 percent increase in deliveries compared to the same period in 2025. The company’s firm order backlog reached a significant valuation of $22.4 billion, bolstered by a steady demand for the E2 family of commercial aircraft and the continued popularity of the Phenom and Praetor business jet series. Management indicated that the production ramp up remains on track to meet full year guidance, despite ongoing global supply chain constraints affecting the aerospace sector.

Let’s take a look at passenger totals at 22 German airports in February 2026. Thursday’s issue will cover Italian airports.

Menzies Aviation reported flat year-on-year cargo volumes for 2025, handling 2.4 million tonnes across its global network of 76 facilities. Despite the stagnant tonnage, the company achieved a record-breaking financial performance, with global revenue climbing 16 percent to surpass the $3 billion threshold for the first time. This growth was primarily fueled by strategic expansion, including the acquisition of G2 Secure Staff in the U.S. and the addition of 63 new airports to its portfolio. While the cargo sector remained stable, Menzies’ overall momentum was bolstered by supporting 5.3 million flights and expanding its footprint to 347 airports across 65 countries, solidifying its position as a leading global aviation services provider.

A senior engineer at a Wichita-based U.S. aviation company has pleaded guilty after attempting to board a flight from Dallas Fort Worth to China with proprietary company data valued at more than $100,000, highlighting ongoing insider-threat risks in the aerospace sector. According to court documents, 57-year-old Junjie “Jeff” Zhang was stopped by U.S. Customs and Border Protection (CBP) in 2019 and initially denied carrying any work-related materials, but agents discovered confidential files, including technical graphs and blueprints, on his laptop and a thumb drive.  Investigators later confirmed he was not authorized to possess or export the documents, which triggered a Federal Bureau of Investigation (FBI) inquiry that had already begun after earlier suspicious behavior during a work trip to China.  Zhang has since pleaded guilty to making false statements and now faces sentencing in July, with the case underscoring how intellectual property risks in aviation extend beyond cyber threats to include employees with direct access to sensitive engineering data. 

Vernon Baker, 41, of Linden, New Jersey, was sentenced late last month to 25 months’ imprisonment and one year of supervised release by a United States District Judge for sexually assaulting the woman seated next to him on a flight into Philadelphia (PHL).

The defendant was charged by indictment in January 2025 with one count of abusive sexual contact on an aircraft and pleaded guilty in December. As detailed in court filings, on October 30, 2024, aboard a commercial flight from Los Angeles to Philadelphia, Baker made sexual advances toward the female passenger sitting next to him.

After the victim refused his advances, Baker took out his ███ and forcibly tried to get the victim to touch him. He then grabbed her ███ over her clothing and untied her pants. Traumatized and shaken, the victim rushed to the back of the cabin where she reported this assault to flight attendants.
