Traveled back from Lyon using Terminal 3 to Stanstead via Easyjet and I must say it wasn't the nicest experience. My girlfriend and I decided to stay and eat in the departures area to use the eating facilities there because I had heard that Terminal 3 had not much in it all of the places available to eat were understaffed resulting in very long queues. Once I got through to Terminal 3 (did so pretty quickly) although security were extremely rude I used my iPhone as a boarding pass and you have to scan it through before going through the security scanner. It seemed I had my brightness on my phone too low for the scanner to be able to scan and all the security person would do is scream at me for about 2 minutes shouting "light light" while I'm getting all flustered. It wasn't until another security person said "brightness" I realised what the issue was. Once through to Terminal 3 it was clear that there is totally an inadequate amount of seating resulting in many people standing. The women's toilets were closed for nearly 30 minutes while they were being cleaned usually toilets are cleaned while still open in all other places I have been. Once going to your gate to start boarding Easyjet scan your passes and then you are put in this kind of holding area while you wait for plane boarding to start. They managed to squeeze about 250 people in an area of 10 meters x 10 meters with no seating and we were standing there for 50 minutes before boarding the plane. totally unacceptable.
