I mean it's fun and an opportunity to do something I wouldn't otherwise do, but it's not right?
I'm going to Oslo for one night. Flights £12.99 each way, as I don't need luggage.
I fully expect to pay more than that for the beer in Norway (one reason for such a short trip).
I haven't flown much in years, but it seems my environmental morals go out of the window when I get invited on trips.
