Late next spring we plan to travel to England. We would also like to see a bit of Scotland. I thought we could fly from Portland, Oregon to London going, and then fly back from Glasgow to return. But at least on Skyscanner, the price difference was quite a bit more than if we did a RT from London. ((We plan to go to Moreton-in-Marsh, then a bit of East Anglia and York and then head to Edinburgh.)
I'm wondering, maybe I need to check specific airlines, or maybe we have to consider flying back from Glasgow or Edinburgh to Heathrow and then head home. I'd appreciate any suggestions.
