RevMan2 Appreciate the heads up. Based on my extensive experience with BA punctuality eastbound I fear that we'll be a tad late so it could get interesting if westbound is as bad. It's tempting to take a later AA flight but that would add another 3 hours to the arrival time at our ultimate destination (Hawaii). There is an alternative routing through Seattle which may be less hectic and I will consider that.
As least the kids are well past the "Are we there yet" phase and there is 110/240V to keep their gizmos alive available on the A380 at least.
