Just a word to save some time...if you clear customs and bio check with less than 1 hour to go you cannot check your bags in at the international terminal.
You have to take them with you on the bus or the 10 mintue walk, and check them in at the domestic terminal.
Normal check in times for domestic flights are 30 mintues before flight departure.
Hence if you clear customs with more than one hour to spare, hang a left and check in all those bags at the international terminal...your bags will be checked and you can lesuirely make your way to the domestice terminal.
If you have less than one hour but more than 40 mintues, tkae your bags with you...and if necessary, jump the queue to check your bags at domestic (loads of crying travel weary kids speeds this process)
If you have less than 40 minutes.....you'll miss the connecting flight!
