I was on the flight before yours mik3bravo.
There was limited information given at the gate and those passengers who ventured to the gate to ask questions, were handed LRVs for 5 Euro. Those who didn't go to the gate, got nothing and announcements for LRVs were not made.
The 1635 departure eventually pushed at 2215.
I had flown out to DUB with CityJet from LCY and thought I'd try the Flybe service back to SEN. I wont be doing that again.
