Flying SFO-IAH-AMS tomorrow leaving at 6am. How early do the check-in counters open? Normally I wouldn't sweat it, but with the holiday rush, the early hour (lounge isn't open for help), and the fact that OLCI refuses to give me a boarding card (the usual international annoyance that happens to me every few months), I thought I should get there early. At what time will the check-in counter open?
Also, am I being overly concerned? At what time would you arrive given the above?
Thanks and happy holidays!
