Flying with Spirit Airlines BOS Terminal was stress-free and a breeze. The check-in was uncomplicated, and the staff were so polite and nice. Seating in the terminal was outstanding, and the signs were superb. The boarding process flowed smoothly, and the air travel was smooth too. I could really tell that everything here was planned out really nicely, and it was smooth sailing all the way there. Very much recommended-this airline and this terminal!
