We don't want to see your vacation time spent at an airport in a foreign country resolving some travel documentation mishaps. So please, take a moment and review these customs and immigration related issues.
Passengers bound for the UK are required to provide their Advance Passenger Information before departure. Don't worry, we'll gather it during check-in.
For those from countries outside of the UK and Schengen area, you can check if you need a visa on the the UK government website.
If you're a citizen or permanent resident of Canada or the US, make sure you've got your permanent resident card or travel document, valid green card, and of course, your valid passport.
Please note that as a traveler, you're responsible for ensuring you have the correct and valid travel documents, including passports and visas, for your journey. It's important to check the requirements for your destination and any transit points well in advance.
