Domestic flight.
I had a choice of 2 flights on same day at time of booking, for same price on basic economy. I booked the later one. Now, 5 days before the flight, basic economy is no longer available, but they are both available for the same price on reg economy (which is $30 more than I paid).
Can I get them to switch me to the earlier one for free, since both flights have always been equal in price comparison to each other?
(I'm not asking about standby, I'm asking if I can call them today on the phone.)
Thanks.
