Personally, I think it will work regardless of duration of flight. I really don't think $150 to $200 is too much to ask in the longer haul markets. They rarely go with an empty seat in first anyway. Most of the FFs are scrambling for First. They get it for free if available. The point is this - too many people call in and ask if they can pay and upgrade - to not pay attention - especially on those RFTCs we so willingly give out. If they are willing to upgrade for money, why not make money on a "free" ticket? No revenue vs. no revenue. Which will win. I think this is one of the more intelligent decisions management has made.
Tom,
Most new endeavors are tested in certain markets. If the company feels they're not making enough money you never hear about it. If the company feels revenue is readily available, you will see a posting on the web or in your next e-statement.
