8 or so on Aloha, 2 on Island air. 5000 miles RT (bargan). But, 2 catches: the 1K line is frequently less than certain how to do this, but always figures it out. My wife has had no such luck with the ICC. 2nd, all they can do is request the seats from IA. You don't know it took until you call back the next day. It always does, though.

If you have access to any of the lines other than the GM line, wait until very late in the day to call; you're likely to end up talking with someone in Hawaii, and they ALWAYS get it right.
