Heathrow is one of the most expensive, congested and lousiest airports I have been to. I spent more than 25 hours combined while going to and coming back from Nepal. I was charged more than $35 for a two minutes call I made from the airport to USA. I know I should have bought a phone card, but I didn’t think it would cost me a fortune even if I didn’t. The main lounge was so cramped that I could hardly catch my breath. I also found their so called ‘toilets’ filthy in comparison to American restrooms. Overall, I was disappointed with the experiences I had at Heathrow - it was quite 'Rubbish'.
