I do not fly every month , but when you park your car to go on 4 day trip and the shuttle picks you up to take you to airport, no one tells you about the app you have to download. Parking lot has Ticketless Parking... everyone was confused and not wanting to to exit gate hold up others. This payment process is not right!
