Do we need a reservation

If it's an early Monday morning flight, that tends to be Bradley's worst day so cars can stack up a bit to get checked in.

You don't, there is almost no situations where the have full capacity.

I never make a reservation. The line to check in is short or nonexistant. It only takes 2 minutes from the time i exit the car to getting on the shuttle to the terminal.

Don't need, but it helps speed up the process.

You can go without a reservation as well though i would recommend making one in advance.

Yes
