After security checkpoints close for the night, all passengers are restricted to the landside areas, and must re-clear security the next day when the checkpoints open. Travellers report that there are some armrest-free benches in the pre-security departure area, but warn that sleep becomes problematic with the early AM opening of the security checkpoints. The nearby arrivals area is quieter and darker, but all seating here reportedly comes with armrests. For uninterrupted sleep, there are hotels near the airport. See Airport Hotels in the airport guide below.
If you are flying solely within the UK, including Northern Ireland, you do not need a passport but we advise that you carry photographic identification with you when travelling, such as your passport or driving licence. This may be requested at certain points in your journey. Children under the age of 16 years do not require identification to travel within the UK.

Other changes include: some airports have stopped curb-side baggage check, anything vaguely resembling a knife or lighter may or may not be confiscated (although lighters suddenly stopped being dangerous a year ago), you're sometimes only allowed one carry-on plus a purse, briefcase, diaper bag or the like, non-passengers aren't allowed past security, all passengers must have a document that looks like a boarding pass at most airports to get past security, you may have to put your toothpaste and shampoo in a baggie that may have to be a one quart size, some parking areas close to terminals are closed. But check-in clerks no longer ask you whether you packed your own suitcase.
