I think the worst leg room of any British airline has to be that on My Travels 763's. Me and the better half flew to the Dominican Republic on one. The seat pitch couldnt have been more than 28" with 1" of recline. Sitting bolt upright for nearly 9 hours wasnt funny and I have vowed never to fly long haul using a charter airline.
A few years ago we visited family in New Zealand and chose to fly via SFO. We flew BA to SFO and Air New Zealand to Auckland. BA world traveler had about 32" seat pitch where as Air NZ had about 35".
