Yes, Saint John’s airport operates around the clock. This means you can spend the night in the airport, specifically inside the enclosure so you may catch your early morning flight. Another reason you may want to sleep in the airport is to avoid paying for accommodation, which can be expensive for most travellers. The ideal place to rest is on the seats with armrests inside the terminal. You can also go to the VIP lounge or use a sleeping bag to sleep on the carpeted first floor.
