Great service, free wifi, comfortable and fast. Also the charger point worked for my phone as it should. The only downside was I didn't get any sleep because the ride was too exicting.

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 14:45 to Cardiff from Heathrow is still not here yet it's running late and no explanation from no one I am not happy with the service. If I turned up late the bus would have left me then I would have to buy another ticket

Unfortunatelly I didn't have the opportunity to enjoy an experience with Flixbus because they cancelled my trip at 10.30PM, 12h before the departure

Hugo D.

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.
