Bad experience with the staff boarding the gate. I couldn’t board with my carry on, personal item and a funny bag. I had to put my passport inside my pockets and put the funny bag inside the personal item. Then after passing the staff pull out everything again.

Frequent flights connect you to London from many cities in the United States, so you can be sipping tea or watching the changing of the guard in no time.
