The SNN-DUB route was a great way for a cash-strapped teenager to experience some transatlantic glamour - I admit some of the best 45 minutes of my life were spent that way - 720s, 707s and 747s. Magical...especially if you had a tight connection in DUB...more often than not the transatlantic flight was late and you get a free re-route via Heathrow/Manchester/Birmingham/Newcastle... 747 followed by 2x Viscounts was not unknown!
One unforgettable day I hopped on a scheduled 707 (EI-AMW) DUB-BFS. I think I was the only pax onboard.
Years later...Kuala-Lumpur to Changi was pretty short in a 747...but no substitute for "stacking over Ennis"....!!
