What happens if an initial booking made several months out is on a partner that levies fuel surcharges on awards (e.g., BA) yet as the travel date approaches, we are able to switch at T-11 to an AA metal flight? Would we get a refund of the fuel surcharges? (Something tells me the answer is "no.") But if the YQ is refunded, this could be an effective strategy (especially for Y tickets) if the current situation becomes the "new normal."
