hi

sorry if this has been posted before. what are some of you FTers' experiences who doesn't have Elite FF membership when asking for an upgrade to first class from an economy seat? if there are still plenty of first class seats available, they're entitled to say "NO" to you, right? it's just that it sucks for me to see those available first class seats not being sit on and go to waste. would it help to show up early at the gate counter and ask nicely? and is it better to ask for it at the counter where you check your bags or at gate counter? care to share??

ps: is there another thread/link that relates to this?
