Mark, this is the airline biz. You may recall that United started hyping their wonderful new Polaris long ago with an incredible marketing blitz … the planes, however, never actually got online. A few, then a couple more... Polaris planes have been staggering onto the tarmac for probably two years. Since I understand that some of their business cabins are 2-4-2 … yes 2-4-2 … I've always expected some kind of revolt from the loyal passengers. In a normal business, this would quite embarrassing, but with an airline it's business as usual. I always know that by booking long-term, I'm subject to this kind of issue. So far I haven't been caught but It's just a matter of time. You do have time before your trip, so hope for the best.
