Flying from the airport in Rockford, Illinois? Once you check in, there’s a good chance you’ll go through a short security line and then board a bus that will drive directly onto the tarmac at Chicago’s O’Hare Airport.

And now, if you’re flying Delta or JetBlue out of Boston, you’ll also clear security before ever arriving at Logan Airport.

You’ll go to a check-in facility in Framingham, Massachusetts, check your bags, and get your boarding pass.

You’ll also park your car for a lot less, then get on a bus, which takes you past security at Logan, and to your gate.
