Changing Flights

I'm pretty lucky that I'm travelling with two other people, but they changed they're flights a few weeks ago without me realsing it, which means I had to change my flight to match theirs. This meant finding that flight, finding out I couldn't make the changes online, and calling them at 8:00 p.m., only to talk for 5 minutes and be on hold for 30. But, I did get my flight changed, so I will be meeting up with the others from the start.
