3rd a/c is presumably due from 22nd May when the route starts.
Here's hoping for north Italy next. The flight times are fairly late in the day, so presumably this lets them get in 8 sectors despite a 2 1/2 hour flight time?
I'm not an expert on this but I'm guessing if the plane does a few short hops to Dublin or Stansted and back then it leaves time for the 6 hour round trip (inclusive of turnaround time)?
