Quite often if you are very early for your flight they will put you on an earlier flight - best bet is to call the san juan desk as soon as you land and let them know you have landed - they will often hold the 2:30 if they know you have just landed - if you do get told to rush right over, send one of your party to the kiosk (next to Jet blue) while another retrieves the luggage then gets a porter to take you to Air Sunshine. cheers
