This used to be a real pain, as there were no airlines that flew direct from Scotland to Sweden. A stopover was always needed. I've flown all the way down to Paris before and then all the way back up, and that's no fun :-( And it takes so long with the waiting time in between flights too.
Then Ryanair started flying direct to Prestwickfrom Skavsta. Unfortunately both of these airports aren't very near where I live in either country, but at least now it's only one flight even if it takes about as long to travel.
But now I have just discovered that SAS have started flying from Arlanda (about 20 minutes from where I stay in Sweden) direct to Edinburgh. Not only will this cut down the travel time, a great thing when our daughter Elsa comes with us, but is also much cheaper (well not cheaper than Ryanair, but nicer).
Another cool thing about flying with SAS is that you can check in via the internet or using your mobile phone up to 22 hours before the flight leaves. They also have a self-check where you print out your own luggage labels and things, makes for shorter queues. I like it when technology is put to good use :-)
