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

Travelled on probably the hottest day of the week and it was absolutely boiling on the bus. Couldn’t feel any air conditioning coming through. Very uncomfortable journey.

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.
