I blame the airlines too. But the person sitting in front of you pai for a seat that reclines. You are expecting as a right that person to surrender what he paid for, so that you can receive more than you paid for? Pretty nervy. But this seat jamming device should be right up your alley.
I admit. I just do NOT get it. Some on these threads (there are several) insist they get what they paid for, but refuse to allow that others paid for their seat area too. So I’m supposed to be in pain so that someone else can be comfy reclining????
And I paid for a seat and a tray table for my use. The guy in front can take away what I paid for, but I have no say when he takes away what I paid for? As for using the knee protector, no, I'm not that petty, but some around here seem to be.
