The last time I flew I did so with Asiana and had plenty of room to stretch my legs out underneath the seat in front. Have to fly to NZ soon and am worried because Qantas has less space between seats. I know it's only 3 hours but since having knee surgery I cannot keep my knee bent up for more than 15 minutes before having to straighten it out. Has anyone flown the Qantas 737 - 800 lately? Is there room for me to stretch it under the seat in front? I know I can ask for an exit row seat but doubt I'd meet the criteria. Please, no smart remarks about going business class...I'm saving that for next years long haul.
