I have flown this route many times, and always flown a 737-200. However, having looked at OAG, Ryanair now use a mix of 732 and 738 aircraft. Let me know the date and flight number and I'll have a look (it's always subject to change, obviously).
As for what to expect, you'll take off from a 21st century airport and land at a 60s one! No, PIK
isn't too bad, just a little dated... Brilliantly located railway station, too.
If you're lucky you'll land on RWY 13 at PIK
, approach over Ayr and then turn over the sea - you may get to see another plane land as you bank, I remember seeing a Cargolux 744 touch-down last time I flew up there - quite a spectacle!
is a nice little route that Ryanair have created - popular not least because of the rather poor ground-transportation at GLA
(read: no station). I've flown the route before for less than £14 return all-in, and never been delayed. A great way to get to Scotland!
