denny et al; tho many have taken more trips than i, u havent since 9/11 & SARS. i didnt hand my SARS relaese to the right girl & was delayed additional 20 minutes to get back in line.
i would say expect close to 30 if goes well (start to finish), more if high season, give or take. that was in slow season (few tourists on AC anyway). well, then the maya flight was 20 min late, and they had to load up....i'd say (6/14/03) i landed at 12:12 and got to AC by 2:30.
ps - on way back to states, they took my bic lighter and all my rechargeable niCad batteries ($30 US) so pack them in suitcase, not carry-ons!!!!
