Beat the queues at immigration when returning to the UK by registering for the IRIS immigration passport. Here you can waltz through immigration by getting your iris scanned, waving goodbye to queues. Tip: be careful with any luggage you have. If you are pulling a small suitcase it can often be mistaken for a very small person. There is usually someone to hand who can help you or let you through anyway. At least you tried!
Registration details can be found on the www.baa.com website with locations and opening hours of the IRIS desks (The desk at T3 is just to the right of the immigration check before the shops).
