Practical Information

You don’t need a passport for UK domestic flights, although you will need to bring some official photographic ID (such as your driving license). The check-in desks open two hours before departure, and we recommend arriving at the airport at least 90 minutes before your flight takes off. Give yourself extra time if you’re flying during the summer holidays: there’s likely to be big queues at security.

What to expect in London

It’s best to visit the cash machine when you arrive in London: shops in the capital are notorious for turning away Scottish bank notes.

London can be very expensive, although there are some good bargains to be had if you do your research first. Even still, it’s likely that you’ll be shelling out extra for dinner and drinks, and a little more on taxis. The London Underground is a wee bit more complicated than the Glasgow Subway, but there are smartphone apps to make getting around a lot easier.
