We had red tags -- about the 5th or 6th group called. Our tag color was called during our estimated 30 minute window, but it took a full hour from the time our tag color was called until we were thru Customs (and we found our luggage relatively quickly)...I do not recall the exact time we got thru because we were headed to a hotel, not the airport -- but I think it was about 9:30am.

I can tell you that White (early disembark) tags were called promptly at 7am as scheduled.
