Just wondering, what do you think the chances are that other carriers who already don't do a pure revenue-based FF program will change over to like how United are? Specifically I'm wondering about AA and DL especially. Do you think they'll "match" next year or wait and see how things shake out for UA?
And wonder why they didn't go straight to revenue-based FF when PQD came into force instead of doing the hybrid model we had for the past few years? Technical reasons? Something else?
