Flybe resuming DUS from late October, as a daily service operating in the evenings. Probably has better timings than when they last operated the route, so I wish them all the best and hope it doesn't get dropped a week before it starts like HAM did last year...

In other good news Dublin is now showing as ~4 daily again and a couple of flights per day to Guernsey have appeared.
