Further update on the new LCY route. I am no w at the gate. Boarding is from gate 301, although the plane is parked on stand 300 which doesn't have an airbridge and explains why we walked from the aircraft to the terminal building on Friday evening. No exit border check on leaving DUB of course and just security. The 301 gate is less than 5 mins walk from security, and of course as a CE customer you could use the fast track.

So based on all this I would say back-to-back at DUB from the LCY route is fine and you will probably be at the gate with lots of time to spare.
