I had arranged to be in the lounge as I had a 3 hour wait between connections. I gave my flight details and was still able to book. To my surprise, I had to leave the terminal by the exit to go through security at the next terminal to visit the lounge. This understandably took time and I was asked to make sure I left enough time to return to the terminal, where I again I had to go through security to get my connection. I had 45 minutes of not a very relaxing time in the lounge. The lady looking after me was lovely though. I really feel there should have been an explanation upon booking so I could make a decision whether it was worthwhile booking. I would not recommend the service.
