UAalltheway.....you might be able to do that, however, you will have to do it day of departure. Yes, the CSR's are given some leeway but even an agent can switch you to another carrier. All they have to do is print the tickets to paper and Invol/reroute 120.20 you to the other carrier. There is also a way to electronically "push" the ticket over to their system which is also just as easy. There are a few things that we look at before we would do something like this though:
1. The price of the ticket- if you paid alot for the ticket but it is short of a full fare then you might be out of luck as the originating carrier tends to not want to lose that revenue.
2. availability- if the originating carrier is overbooked for the flight you are on, then they would be more than happy to switch you to another. They get out of having to pay out TC
's(travel certificates) this way.
3. The relationship with the other carrier-don't see it often but some agents won't switch you over to a carrier that they don't like...i.e. the other carrier not being helpfull to them when they are overbooked, etc.....YES, IT
Our(CO's) alliance with DL
hasn't been going on as long as our alliance with NW
would be more apt to switch to NW
than to DL
, with any of those combo's, although, I have done it myself and have seen others do it as well. I will tell you this though, you would not be able to do it before your departure date. HQS(headquarters) keeps tabs on these kinds of things and might get that person in trouble...however, day of departure, pretty much, anything goes. Good luck to you...let us know how you make out.
