Is it possible to have two separate reservations merged?
I booked PDX-LAX-DEN separately from DEN-SLC but the layover in DEN is less than 4 hours and the DEN-SLC switched from a non-ExPlus CRJ-200 to a CR7. Is it possible to have the two reservations merged into one so I can upgrade the DEN-SLC with the same 2 e-500s I'm using for the PDX-DEN trip?
