I'm sorry, what?
The parent said he is 6'3 and I can sympathize as I am also 6'3. There is literally NO ROOM for the person in front to recline, my knees are already jammed hard into his seat and getting bruised. The gap in between seats is too small.
Now on longhaul flights (between Aus/NZ and the US) economy seats DO have more room and even fully reclined I fit fine. (It's still a small uncomfortable space, but my legs are no longer being fucking crushed like on shorthaul flights in the US.)
I literally could not fit my legs into the space infront of me on an LAX to SFO light. It's ridiculous.
Flying in economy is only for short people now....
