I really wouldn't do that. For no other reason than, what if your flight out is delayed? What if the first time you see each other is when you find your seat? Is it even a flight where you can pick a seat? London (Gatwick, Heathrow, Luton, City?) to Stockholm, I'd doubt it, and you may end up at opposite ends of the aircraft.
There are so many ways that could go wrong, logistically. Not to mention, while it isn't exactly creepy, it's definitely a high pressure situation - first dates are hard enough without the added awkwardness of one party flying to another country for absolutely no reason other than 'it sounded romantic'. Save the romance for when you know you two will work out.
And being on a plane together and being on Skype together are two very different things. You can't just up and leave a plane, for instance.
