Booked my mom EWR-CDG and was gonna put her in E+. The difference between a normal E+ seat and exit row 21 is about $20. My question is, is it worth the extra $40 for the few more inches in 21. I've heard that sometimes certain planes exit row's have less padding on them. If that's true then that may not be comfortable for 8+ hours. Can anyone tell me if the exit row's have less padding and say row 10 might be more comfortable in the long run.
