Given your arrival times you might want to call AS 24 hours before to confirm your flight AND tell them that you are arriving that early - often we arrive at 2:15 and they will hold the 2:30 flight to put us on it as we usually arrive at their ticket location by about 2:45 - then we just go with the 2:30 flight passengers on the delayed 2:30 - this helps us and them as they get to carry a full load and leave room for last minute passengers on the 5PM - cheers Brian
