I don't understand what going on with Flybe SEN-DUB. Maybe It already arrange for Easter holiday before it collapse?
Weird development here, the flights on April 3rd to DUB are operating with the same times and flight numbers (!) as flights that operate from LCY. There are no BE LCY-DUB flights on April 3rd so either they cannot/will not use LCY on this day (building work?) or they have been input into the system incorrectly.
