I hate the airports when they put us on bus to change terminals. Unfortunately, Heathrow is one of them. When I was on the bus, the bus driver purposely drove over Indian workers who were working on the ground and the Indian workers wanted to stop the bus to argue with the bus driver but the driver did not stop.

I have used LHR on a large number of occasions and I will continue to use because I have no choice. Yes, it is big and spread out, but getting around is not difficult but could be made easier. The food outlets are varied but very overpriced. If you are going to be here for some time, bring food with you, doing so will save you lots of money. Huge numbers of retail outlets, again overpriced, but you can pass a lot of time window shopping. Easily the best thing about this airport are the staff. I have nothing but praise for the employees here, very helpful and friendly, never once met a rude staff member here. This airport is functional, Terminal 1 needs to be renovated but considering its size and the number of passengers that pass through it copes very well. 8/10 for the airport. 10/10 for the staff.

As air crew I travelled to and seen loads of airports worldwide and I m sorry to say LHR is not anywhere near the best. Too big, too confusing and probably the worst place in terms of connecting flights if you don't like to walk for miles. That is unless you are flying Star Alliance as all its airline member are at Terminal 1.

Never had a problem at Heathrow. It's just run by an awful company! Terminal Five is amazing! But LHR has some amazing plans ahead. It's always a pleasure flying out of Heathrow. Frankfurt was a mess last time and as for CDG, well, speaks for itself. I admit there are better airports, but LHR is an amazing place, it's huge, it's busy, it had Concorde!! Home to BA, I love LHR!

Compared to other European international airports, such as Frankfurt or Amsterdam's Schippol, Heathrow is poor. In its defense, it has improved with the opening of Terminal 5, as now there is less traffic going through Terminals 1 and 3, so times spent standing in check-in and security lines has decreased. However, it's still not great, with the emphasis being on shopping, not flying. If you are using Heathrow as a lay-over to catch a connecting flight, try to book all your flights with Star Alliance partners, as almost all these Airlines are based at the same terminal (Terminal 1). If you do have to change terminals, try and book flights that leave you a four hour lay-over. Changing terminals can be done in less than four hours (obviously), but by the time you factor in security checks, finding your gate, getting something to eat, etc. four hours would be my recommended stress free time window. If you are getting a domestic flight, prepare yourself for the wait in gate, wait in gate, wait in gate and then mad sprint for boarding when they announce your gate five minutes before boarding. Oh, and domestic flights through Heathrow are very rarely on time.
