Just curious for anyone who's done a quick turnaround in GVA, is 90 minutes enough time to get off the plane, go through customs, and then get back on? If it helps, I'm on the UA 974 leaving SFO at 8:50am on May 23rd, and on UA 8875 from GVA on the 24th. Flight 974 gets in at 8:00am on the 24th and 8875 leaves at 9:30AM the same day. Good idea, or should I cancel the run?
