National Express Cardiff Heathrow recent customer reviews
I'm not satisfied. I was supposed to get to Terminal 4 at 04:00pm, but I got there at 05:38pm despite the fact that the traffic was mild. It was my first time to Heathrow, the feeling and experience wasn't good.

Staff were nice. Journey was slow and bus was cold, especially the emergency exit row where we first sat. Arrived 30 mins late, which isn’t great for the airport
