> The very second that United knew they had 4 employees they had to acccomodate, their computer system should have immediately confirmed those 4 employees on flight #3411 first such that the plane only shows 66 available seats instead of 70. (Computers doing math for the win!) That way, either 4 of the customers get denied a boarding pass at the check-in kiosk, or they get denied at the gate that scans the barcode be…
>, but the 4 crewmembers are in the employee lounge and just a 3 minute walk from the gate. They can still make the flight before all the passengers are out of the jetway... In that case, I'm saying there would only be up to 66 (not 70) paying customers in the jetway. This still leaves 4 available seats for the deadheading United employees. In other words, don't render those 4 extra United employees "invisible" to th…
All 70 passengers are in the jetway or on the plane. Say, 40 are on the plane, but 30 are still in the jetway. At that moment, United discovers that it needs 4 crewmembers on that plane. They have 4 crewmembers sitting around in a crew lounge in that terminal of the airport. They can walk to the gate in 3 minutes. 3 minutes from now, some of the passengers will still be in the jetway, waiting to board the plane. Now what?
It's not enough to just improve the computer system. The timing window still exists, even if it's smaller. What you need to fix this is some kind of business rule, like "You can't deny boarding to a passenger who's already in the jetway, no matter how badly you need their place for a crewmember".
