A landmark contract in May this year pushed top-of-the-scale pay for United Airlines flight attendants to $100.13 per hour for experienced crew by the end of the five-year contract. In addition, they added boarding and sit pay and included a signing bonus pool of close to $740 million, according to CNBC, sharply raising the cost of every pay-protected trip. So why did United, after just a few months, have to start policing its own flight attendants?

United’s flight attendants now risk termination if they intentionally exploit rolling flight delays to gain pay protection on trips they do not work. It seems that it is not a labor dispute per se, but United Airlines is quietly building a data-driven enforcement machine to claw back the margin it just handed away in the new contract.

A Flaw In The System?

An internal memo in September 2026 warned the airline’s 28,000-plus flight attendants that ‘conflict trading’ is ‘impermissible and fraudulent’ and can result in termination. It warns crew members against using flight status information and schedule changes to benefit from rolling delays, and picking up trips they know will be dropped due to crew rest times and therefore receiving pay without operating the flights. The memo describes it as a misuse of the contracted pay protection scheme.

A rolling delay occurs when departure times are pushed back repeatedly in increments, instead of being declared a long delay. Under union contracts, flight attendants can trigger additional compensation when the schedule is updated, and they are notified of the delay. This is especially true when duty periods are extended, or there are long gaps between flights. In this case, some flight attendants may be working the system to trigger payments when they know the trip won’t go ahead.

Flight attendants can trade assignments with each other and pick up available trips, giving them flexibility in their schedules and allowing them to work extra hours. View From The Wing explains that a flight attendant works a trip, finds out they are getting back later, and picks up a trip for the next morning. The computer allows it until the delay is entered; the flight attendant doesn’t have enough rest time, so the system removes them from the trip and triggers the pay protection payment. This is the loophole in the system.

Trip Parking And Trading

The memo also lands alongside 2026 disciplinary actions against ‘trip parking’ and selling desirable trips to colleagues using code words like ‘cookies’ or ‘hugs’. There was also a crackdown on reserve crew being ‘out of position,’ or not physically at base when duty starts, signaling a broader shift toward data-driven enforcement of the union contract and stricter scheduling. Trip parking is when a flight attendant temporarily puts a trip on another person’s schedule to trade when it wouldn’t normally be possible on their schedule; then they reacquire the trip.

Senior United Airlines flight attendants have previously been found selling desirable trips to younger colleagues. They have seniority, so they can pick the best trips. Picking up trips and saving them for friends or colleagues is also not allowed, as is acquiring a trip to broker it without the intention of actually flying it. The memo aims to deter flight attendants from using detailed delay information, scheduling tools, or trading platforms to engineer outcomes. United terminated flight attendants in July over alleged trading violations tied to this pattern.

It is a gray area: a delay or cancellation is likely, and crew may use that information to choose trips that show delays, but the contract protects their pay if the flight does not happen. United’s management concern is that intentional ‘gaming’ of the system is happening and enabling guaranteed pay despite a flight attendant not working. In theory, as View From The Wing gives an example, if a trip is five hours and a flight attendant’s hourly rate is $60, that’s $300 paid for a canceled flight.

What Are The Consequences?

The airline is not trying to remove the pay protection scheme, but to stop conduct that appears to exploit the system: someone deliberately looks for soon-to-be-delayed flights when a schedule change is likely, and the trip gets canceled. Union sources told The Traveler that pay protection was negotiated to address the unpredictability of airline schedules and should apply when a flight attendant is genuinely scheduled for a flight and is later disrupted.

Union guidance also says flight attendants should not try to manipulate schedules for compensation, as they could be accused of dishonesty or misuse of the systems, which would also put contractual protections in jeopardy. United has warned that this conduct falls outside the intended use of the pay protection provisions negotiated for when schedules go out of control.

The airline says crew must have the intent and ability to work any trip they pick up or trade into, a principle it claims has been upheld in multiple arbitration cases. United management is essentially saying some flight attendants pick up trips because of delays, with no intention of working them. The airline states in the memo, as reported to One Mile At A Time:

“As United employees, we often have information about delays or cancellations available to us before our systems are updated and before that information is available to our customers. Using that information for a financial benefit is an impermissible trade practice.”

“You must have the intent and ability to operate the trip being picked up or traded into. This principle has been affirmed in multiple arbitration cases. Violating it can result in discipline or termination.”

The New Contract

The new five-year contract was ratified in May this year and gave approximately 31% more of the average wage, according to The Travel, increasing the flight attendants’ salary. Added to that were the long-contested boarding pay and compensation for lengthy delays and time sitting between flights. Boarding pay is paid at 50% of the hourly rate for the scheduled boarding time, according to The Traveler.

There is extra pay for when scheduled ground time between flights exceeds two and a half hours. Sit pay is meant to compensate for extended duty periods spent waiting between duties. These are combined with pay protection rules when trips are delayed or canceled after being assigned due to things like weather or congestion, so that flight attendants are not penalized for things outside their control. The new contract also included better scheduling and more job security.

The internal memo from the airline shows an emphasis on discipline and possible termination that could add friction to the relationship between the airline and its flight attendants after years of bargaining for an agreement between the airline and the Association of Flight Attendants-CWA. The final agreement makes it one of the highest-paying flight attendant jobs in the US and is set to be a benchmark for future flight attendant contracts.

When Is It A Violation?

If a trip is arranged in advance, an unexpected delay occurs, and the second trip becomes impossible because of crew rest requirements, the pay protection scheme kicks in. Domestic flight attendants generally require 12 hours of rest at their home base between assignments, according to The Travel. When trips are scheduled closely together, it may look tight but is workable; a delay would also be acceptable to receive pay protection and would not be seen as misconduct.

If a pick-up occurs during a delay, it is not a violation as long as there is enough time to work the new assignment. The memo is aimed at someone who knows with certainty they won’t be permitted to work the trip when the system updates. The issue is when a flight attendant knows a delay will make a trip unworkable, picks up the trip anyway, and collects the pay.

Updating the system with operational information that the airline already has would prevent some of these dubious practices. There is a loophole in the system, and flight attendants may have access to operational information before the scheduling system catches up. After previous issues with selling and controlling trips, the airline has used software designed to spot suspicious patterns of trip trading. The current scheme relies on a lag in United’s scheduling system.

The Bottom Line

United Airlines has not disclosed how many flight attendants face discipline beyond the July terminations, and the union has not issued a public response. While trip trading is standard across the industry, United’s policies prohibit monetizing those exchanges. Similar concerns over the trading of desirable trips have emerged elsewhere within the industry, including at American Airlines, where the practice has also led to further scrutiny and disciplinary action.

Furthermore, conflict trading to manipulate the schedule and gain from pay protection without flying is somewhat dubious. The scheduling system’s reporting lag remains the underlying vulnerability, and until United closes it, the incentive to exploit it could persist. United has reportedly warned staff about the practice for years and previously introduced software designed to identify suspicious trip trades.

The controversy comes after the new contract, which pushes the flight attendant hourly pay level to the highest it’s ever been at $100.13 by the end of the five years, for experienced crew. In the case of conflict trading, unless the underlying system is examined, the incentives that encourage these practices will probably remain.
