This is the issue I'm writing Bob Sokup about. I would think well thought out snail mailed letters from WorldPerks members at this point may convince him to change his mind.
If anything, Bob should be pushing to EXPAND International First Class options to all SkyTeam partners who offer First Class, not just maintaining the soon-to-disappear F award option on MH. OneWorld and Star Alliance are looking better and better for the business traveler who spend the bucks (the people that Bob & co. really care about) and accumulate the miles for the worthwhile perks.
TTU is okay for many things, but nwa.com website comments in this particular case will be ultimately ineffective (actual rational arguments and reasoning don't translate to the dry "we got this many complaints about X and Y" statistics that end up on some V.P.'s desks).
Please write out a short letter to Bob Sokup today, while there's still time!
