Need advice:
I have only one Amex PRG (wife's name): previously selected United and did MPX last year for travel credit. I understand that MPX is done now, and we are not traveling on United much, so don't want to do United GC (or gift registry). Since it is a new year and we can change the airline, can we change to SW (travel on SW more) and buy SW gift card to get $100 airline fee credit? If yes, do we buy the GC directly from SW site? After buying, can we just add to our account and keep using it to pay the taxes/fees (flights are mainly booked using SW points).
Thanks.
