Hey guys, thought this was pretty interesting. I called CO to take advantage of Platinum benefits and make a free change to an award reservation today. Without too many specifics, the award is a C award from North America-South Asia. I actually wasn't even adding any flights - simply removing some extra intra-Asia legs that are no longer going to be used. The legs that were removed were entirely within the South Asia award region, so the origin/destination regions did not change. When the award was booked, it cost 125k miles/person - as expected for a C award from North America-South Asia. Here's the kicker: when I called today, since I was removing some legs, they had to re-ticket - at which point, they wanted to charge 135k miles. When I asked for the breakdown on why, after about 20 minutes of me on hold as the agent was on hold with a supervisor, it turns out that the reason was the one CO flight on the itinerary: apparently, from now on, the claim is that CO/UA will be charging F miles for the CO BF cabin. Did I miss something? Was there an announcement about this when the announcement to keep three cabins was made? The original phone call ended up working out - or so I thought - when they said they'd honor the original pricing (125k miles/person) - they offered to do this without my asking (though I was ready to strongly insist that they would do so if they hadn't made that offer), and I received an email confirmation with the re-ticketing at that price. However, as I was typing up this summary, I received another email confirmation - showing that it had once again been re-ticketed, this time with the 135k miles/person price. I am now back on the phone with CO, attempting to get this situation remedied. Once again, I am on hold, as the agent is on hold with a supervisor. To quote mwg25 (I described this problem to her in an email, before coming to MP with it) - "If CO BF is, from henceforth, to be counted as F for pricing purposes, that is obnoxious. If that is to pave the way for ALL *A 2-class front cabins (AC, etc) being counted as F, that is unconscionable."
