I took this flight only once, in order to connect with the 787 IAH-SFO flight before the fleet was grounded. It was worth it, but less than pleasant. On a few occasions, (when departing YYZ from an adjacent gate) I've overheard a gate agent asking O/D passengers to give up their seats and take the later flight to IAH due to headwinds and weight restrictions.
