(after a quick google and searching on flights aggregators)
Flying out from Birmingham will add at least an extra transfer at a major hub (atlanta, houston. newark...)
If you can make the drive to Atlanta (3 hours) , then you can reduce the number of transfers to 1 (mostly somewhere in Europe like Paris, Heathrow...).
At that time of the year prices will be a little bit higher than other time of year; but the earlier you can book, the cheaper it will be.
Good luck with that.
