Once
Account profile
Set this up once. We need this before we file a drop. We tell the airline we are Fareward, acting for you. We never say we are you. We do not re-ask this when you add a trip.
Fee card
Card on file
This is the card we charge later. You pay 20% of the savings only after a credit lands. $0 to save the card. Not the optional booking-card last four below.
