Wasn't aware that was a perk of Y/B fares. I've never purchased one.

Then by all means, I say they should also board with SE/J. Chances are most people who purchase Y/B are probably also FFers...

Although in a 5 tier system (hopefully it won't be that complicated...) 'priority' doesn't necessarily mean 1st group. So let the debate rage on.

And again, thanks for participating in my education.....
