For EWR fliers who drive and park in short term parking:
How do you handle pre-booking when you don't know if you are departing from A or C? Looking at my flight, it seems to leave from A or C depending on the day. Any suggestions?
To clarify: I am looking for UA specific guidance (e.g., is there a way to determine with greater accuracy which terminal or is there a trick to use when booking parking?).
If you're booking short term, the prebooking is for for any of the 3 lots A/B/C. In other words, take your best guess -- but if you booked for, say, short-term C, and you end up needing to park at A, no problem. Same prebooking works - no changes needed.
Good luck keeping track of where the flight is departing from -- my experience is that the terminal sorta "locks in" a few hours ahead of the flight, but I guess always be ready just in case.
