>Any advice?

Here's the thing I struggle with -

1) To make bumping manageable you want to travel with carry-on only.

2) I'm 6'3, 250, so I can't put anything under the seat in front of me - Has to go in the overhead bin so I can have every inch of leg space. (I've been known to accidentally kick the feet of the person in front of me.)

3) When you 'volunteer' you usually don't get picked because there's dozens of volunteers, but you're the last to board, so all the bin space is gone.

I hate the pressure that comes with the wait... knowing I'm likely boarding, and will likely have nowhere for my bag
