Assuming my flight lands on time I have 2.5 hours to get from T1 to T3. I'd quite like to see the Upper Class check-in area so will probably go landside anyway as 2.5 hours should be plenty time to see that area - get through UC security and into the CH for a drink and some breakfast.
Will they reprint my BP to replace the one BD give me @ EDI with a fancy VS UC one. Like to keep these things.
