But the point is , was it from Gla that the other carriers operated there and back to SSH. ? The extra 20 mins (at least) northbound makes a return flight to Gla very close (or is out) when considering the max FDP on 2 sectors - even on a level 2 variation . I'm still not sure how Gsm did it either , which was on a slower 737-700 i think , there must have been a lot of discretion reports!
Yes! I've done it myself GLA-SSH-GLA on a 752. I know it's weather dependent etc but the flight was just 5 minutes longer on the return sector than the average SSH-MAN journey.
