Well, at least they notified you. We flew to london on American a couple of years ago, had bought our tickets 8 months in advance, and they changed our departure time from LAX from 7 pm to 6 pm without notifying us! The only reason we found out is because the day before our flight we ran into some friends who were coincidentally flying to London on the same day on the same airline, and were leaving at 6. I thought it was weird that there would 2 transatlantic flights like that within 1 hour of eachother so I checked into it. Can you imagine?!?!

Actually they didn't notify me. I just went online and happened to see it. Meanwhile I suppose since it's only departing 5 minutes earlier, that's no issue, and frankly I don't mind getting there a little later in the morning.
I could have sworn that I had looked before and found the current flight did match that schedule, but sure can't find that now.
