But really, I had no idea so many people care where they sit.
But YOU care where you sit ... with your kid. Why wouldn't you assume others care too ?
There are lots of reasons people want certain seats - leg room, medical reasons, to sit with their companions, my kids like window seats so they can sleep (long flights), tight connections, etc. I think the only seat people don't want for a reason... a middle!
Having said that, don't get me started on the people who stop in the first row, put their bag in the overhead, and then walk back to their seat in the back?!?
I also used to take the Greyhound bus often, where you can reserve seats, but I never had a problem with people switching for me to sit with DD, and I often switched to let others sit with their kids. (That's a 4 hour trip, compared to my 1.5 hour flight). I figure I'm an adult and the needs of a child trump mine, but that's just me. I know now that there's some who have serious reasons for needing to sit in a certain spot, but that can't be the whole plane full of people, right? I mean, I doubt people who have reserved seats will be asked to move, when there must be a lot of people who don't reserve. But I'm just guessing, I admit I don't know how many people reserve.
Did you have to pay to reserve those Greyhound seats ?
I think that's where the sticking point comes in. When people have paid to reserve a "specific" seat - especially an aisle, to be asked to switch to a middle for a family's convenience is unfair.
As for the "needs of the kid trumps the needs of the adult", what if there is a tight connection because of a delayed flight and someone asks you to switch from 4B to 24B? Because of other flight problems (and a cancelled flight the night before), this is the only way you can make an important meeting and you are hoping beyond belief to make the connecting flight. In that case, does the needs of the kid trump the needs of the adult ?
I just think it is hard to make blanket statements - there is always an exception to every one of them.
"most" of the time, it will work out (as long as you are willing to switch aisle for aisle or window for window!). However, don't just count on the kindness of strangers. When it happens, its a bonus, not a given.
