I have a flight OW to Maui with one stop for 2 people. They are changeable tickets and a nonstop same day is not that much more for individual ticket right now. But when I try to switch flights, the price bumps up another $100 pp. since I'm booking for 2 Can I some way cancel the flight for credit and then book 2 individual flights for the savings using the credit?
