Both times, a change was made to my reservation (once, an involuntary rescheduling and once, an upgrade).

I'd rather just check in at a kiosk tomorrow than deal with yet another phone call, but will I have problems?

(Also, just curious: "API OK" has started appearing on my boarding passes; what does this mean?)

Thanks!
