My sister and her hubby are joining me in Scotland for a trip with our parents, but they are also going to Greece to visit her husband's family. So they have a weird itinerary - they want to go either:
Washington DC - Greece - Edinburgh - Washington DC Or Washington DC - Edinburgh - Greece - Washington DC
Initially the quotes I'm finding are as much as $1500. I'm spending about 860 to get to Scotland, so I'm surprised that it's doubled. Any ideas on how to bring the cost down (they're flexible - maybe a train somewhere in the equation)? I know Greece isn't that close to Scotland But any tips on inter-Europe airlines or options to try would be welcome!
