A modern relatively comfortable airport. Also extremely busy with many families starting or ending holidays there which adds to the chaos in the check-out lines (lots of overweight baggage on the way out and far too few attendants at least at Delta). After checking in getting your bags weighed etc. you need to take all of your bags to a security area to leave them off for scanning (agents said to just leave our bags and leave which seemed to defeat the purpose of security; also not clear what would prevent one from adding items to their luggage to get around weight restrictions). Security line was relativey quick for us but have heard it can be very busy. Plenty of options for shopping and dining but far fewer once you go through security and take at train to your individual terminal. Returning a rental car can be a bit confusing since some companies have their return facilities next to the terminals (need to walk) and some are off-airport. Worse when we stopped to top-off the tank of our rental car several blocks from the airport entrance and with no price signs outside the station we found only at the tank that gas cost TWICE as much as we had paid several miles away. The attendant explained that the higher price was due to it being "on airport property." Sounded like a rip-off (fortunately we were buying just a gallon). We were in the area of hotels and shops and restaurants but not within the airport itself. We had flown into Jacksonville when we arrived in Florida and would likely endeavor to use it or perhaps Daytona when departing from the area again unless we wee going to be based in Orlando.
