So I used to do the public transportation route or have someone drop me off.

Now I pretty much exclusively fly out of LGA and always drive my own car and park in one of the off site lots with a free shuttle. Use the website "Airport Parking Reservations" which will search all of the lots and usually a few have deals.

It will cost about ~$15/day and the best part is the convenience imo. Park get on shuttle go to plane, land get on shuttle get in your own car and drive home. No struggling with Uber drivers who don't want to drive that far or rushing to get on a train etc.

The savings along on flying out of LGA instead of Bradley make it worth it. At least that has always been the case for my destinations.
