Sorry if this has been asked already and I missed it. Have a flight in a couple of days to SEA, and flights appear to go from A vs C unpredictably. My flight still doesn’t have a gate assigned but I’m going to have to reserve parking soon. If I reserve Terminal C and it turns out my flight is going out of A, can I use reservation to park at A since it’s all same pricing? Or do you absolutely have to park in your specific reserved lot? (IE, will the QR code only let you into the specific lot you reserved)?

EWR requires booking at least 24 hours in advance unless you want to pay an extra $26 per day and not even be guaranteed parking. Which is really annoying when you don’t know what terminal you’re going to go out of.
