I never used that app. But how would it make the process faster?
Well there seem to be many one stop flights from Cancun to Charlotte/Dallas/Miami to NYC. Lot of these layovers are between 1.5 hours to 2 hours. Then there are some that are 2 to 3.5 hours etc. But what is the reason for people missing their connection usually? Because if you have checked luggage and no global pass, then will you most likely still make the connecting flight? If there is a delay in any of these things, then what happens? Someone mentioned the airline will book you on the next flight for no extra cost right? But this could also mean the next day most likely right assuming the flight from Charlotte to NYC will be an afternoon or evening flight? I don't mind being early and waiting a bit, but it seems 1.5 hours or so is very tight in this situation? So it would only for people with no checked luggage and global entry?
Would like to know what is the minimum amount of layover someone should want if they have checked bag and no global entry based on their experience.
