I'm fairly sure this should have been posted in the Grumpy Old Men Section but here goes anyway:
Thomson Package for Fifi's Dates from Gatwick = £ 600.00 per person (Well one to Fifi and DianeT)
Thomson Package for Fifi's Dates from Glasgow = £ 732.00 per person.
Price of 4 flights from Glasgow on Fifi's dates = £ 1,403.92 !!!
That's basic cost - no excess baggage allowance,meals etc.
