Unless you are extremely unlucky and a whole bunch of people book on the same flights you want Owen, it shouldn't go up significantly in 4 days. From your previous posts I'm assuming you will get the daytime flight back. I believe this is proving a big hit with U.S. visitors. It's also got about 40% less capacity than the other flights so I'm guessing that's where you're getting pinched? Fingers crossed for you anyway. Let us know how you get on.
