Southwest and ExpertFlyer
Hello,
It seems that I bought the last remaining ticket on a non-stop from BWI-CUN. I went to add my companion - and it was sold out. I've since booked the companion on a non-direct flight, but want to change should a seat become available.
In ExpertFlyer, it seems that there are the following fare buckets: R,S,W,Y,L,B,Q,H,M,T,N,K,O
Does anyone know which fare class will open up if a single seat becomes available? Has anyone had success with an international seat alert for WN on ExpertFlyer?
