No Easyjet complaints, the flight was ok but bumpy due to the weather - However, Manchester Airport completely messed up this journey. * The aircrqft was parked at Gate 11, the gate call was made for Gate 11 but then the gate changed we were sent to a bus gate (20) the photo ID verification started late, delaying the flight. We had to board the bus in heavy rain, to take us to Gate 11. * The weater was stormy, there was no rear steps as is normally the case with Easyjet, presumably the airport decided not to provide them. * Rain was torrential, and due to front steps only, we all got soaked standing on the front steps, we were forced off the bus into the rain.
