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

The journey was super easy with convenient pick up location and really good connection at Heathrow to the airport terminal. It would be nice to have the stops called a little louder as we couldn’t hear at the back of the bus.
