ElNino:
Just shut up and go home!! I am a regular FR customer and use them for all air travel I do (about 20 flights per year) and have flown on Dublin-Scotland routes. All I can say to you is that the service has always been spot on. Regarding the price guarantee, I think you'll find that FR flight times don't differ massively from Go's.
In the 16 years of operation FR lost IR£ 20,000,000 from 1985 - 1991. Last year alone, Go lost £70,000,000 - just get your facts straight will you!

Yes FR fly from PIK for next to nothing but also got a discounted deal from the BAA for EDI, which Go does not have. They wouldn't have started the route without this discount.
Go were incredibly naive trying to enter Ryanair's home turf and got what they deserved.
