I would ask where you purchased the Travel Pro if the battery is wet or dry. And maybe if there are specs that include the battery information for your particular scooter that would be helpful to print out and have with you when you travel. You need to be prepared, as the airline agents do not always know so if you have a printout of your battery information, that would be helpful for them.
Once you find out, contact your airline to verify they allow the type of battery you have.
If you are going to be on American again, you need to contact their Special Assistance to ask:
