I would settle for some nominal amount - maybe $1,500 to $2,000 - to not even book a flight on their system.
Last year we “settled” on $900 each for a taking a later DC to Charlotte flight, but still made our same connecting flight home. Just booked flights to Ireland and a separate stateside trip for one of us. We did give up first class seats for middle coach seats, but I’d say it was well worth it.
