All in all I travel Jarvis Air and I like them - this recent trip from JFK to Miami a nightmare. They do not give you enough time between flights to get to the next gate. I thought I was going to have a heart attack trying to RUN from where I landed to another terminal !!!!!! - If I recall I landed in terminal B and had to go to terminal D. That had to be a 2 mile walk and one monorail ride. This is insane. If I did not run I would have missed the flight since you cannot get there in 40 minutes. I cannot run like a teenager anymore. I could not catch my breath. Any "shuttle rides" were all filled and I was dragging luggage. What a nightmare. Airlines should realize you cannot get to a gate 2 miles away in 40 minutes. Vacation was great - getting there & back no so great. Be prepared if your doing this trip to Key West - be alert about your layover time and length to walk. Maybe you can make arrangement ahead of time for assistance (?).... Key West however was GREAT
