Covering how to prepare yourself for the turmoil of air travel this summer – since so many flights are cancelling, and there are few seats available for rebooking – I suggested booking a backup itinerary using miles for travel later in the day or the next day, and then cancelling the award ticket when your planned flight works out.
However I was asked, “Isn’t United charging for redeposit?” The answer is no, and it wouldn’t matter if they did.
