I'm booking tickets from PIT to PSP next month. Expedia has a PIT-IAH-PSP (that CO offers too) for the trip to PSP. For the return, Expedia offers a PSP-MSP-PIT (NW metal) that CO doesn't offer no matter which way I search (price, schedule, multiple destinations). Expedia fare is booked in S class and I don't want to book it there for obvious reasons. Any chance CO will offer this fare if I call them (and hopefuly V/U class will be the same) ? Does this qualify for CO's best fare guarantee?
