American Airlines glitch allows pilots to drop 12,000 flight assignments

• Yes, but: On Saturday, 28% of American Airlines flights were delayed, according to FlightAware.

Context: About the same percentage of Southwest flights were delayed over the weekend.

What happened: On Friday night, American's trip-trade system allowed flight crews to opt out of some of their scheduled flights, according to a statement by the Allied Pilots Association, the union that represents American Airlines pilots.

• The union said the airline reinstated about 80% of the scheduled trips — without an agreement from the pilots.
• The airline and union are now discussing additional pay for pilots whose dropped trips were reinstated, the Allied Pilots Association said.

Flashback: Something similar happened in December 2017, and American offered pilots 150% pay to pick up assignments.

Between the lines: The blunder comes as the pilots union and airline continue fraught contract negotiations.

• Most recently, the airline — which produced nearly $9 billion in revenue, but a net loss of $1.6 billion, in the first quarter of 2022 — offered pilots a 17% raise.

What they're saying: "Once again, AA's operational mismanagement is at the heart of an issue that will soon go public," Ed Sicher, the president of the Allied Pilots Association, said in the union's statement.
