All the UX questions...

As I posted in the $50 standby thread yesterday, I happened to be working for another agent yesterday and was working UAX. A high frequency market. Plane was loaded, the arrival airport had flow control delays...it sat for over an hour. The plane was de-boarded at about 70 min, and given a new dptr tim for 50 min later. In the meantime, the next flight (mainline) to the same dest boarded up maybe 60-90 min after the RJ. It was ready to go when the arrival airport was able to move up some dptr times. It left long before the earlier scheduled flight as they didn't deboard. My flight boarded up again, sat for 20 min, before getting clearance, and I believe it arrived about 60 min later than the one that was scheduled to leave later. Unintended consequences of consumer protection. Not saying it was a bad call, just that the policy can have negative effects, like the carriers who have stated they will cncl flights.

So yes, at stations where UA operates the UAX flights, UA follows the UA rules and applies them to the UAX flights, as well as the "flight of note" compensation policies for all UAX flights, as that is done by UA WHQ.

I can't speak for stations where UA contracts out their service to an express provider, but I am willing to bet that UA corporate polices with the subcontractors require them to follow UA rules, as the flights are marketed as UA and UAX is not operated as a codeshare, but almost as a subsidiary, with UA policies applying except in a few remote areas (certain baggage rules for example where the UAX carrier has stricter rules filed with the DoT.)
