It appears to me that UA/CO missed a detail on their new baggage fee structure. As a current CO Gold Elite, I get 3 bags up to 70 lbs. each between my home in Costa Rica and the USA. If a bag weighs over 70 pounds, however, I must pay the same overweight fee as any non-elite passenger - $400. A non-elite would pay $200 for a bag weighing 51 to 70 lbs. and the same $400 for one weighing 71 to 99.9 lbs. Logic would lead one to the conclusion that my charge for the 71 to 99.9 pound bag should be $200, since my first $200 fee is waived for the 51 to 70 category. $200 for under 30 lbs. is absurd to me. $400, on the other hand, will sometimes pay for me to make another round trip run with 210 lbs. total in free bags. I will never again carry one pound over 70. It is unlikely that I would have ever done so for $200, but there could be a time when that might be reluctantly justifiable. There is NOTHING 29.9 pounds or less that I could carry to justify paying $400 dollars. I found this out the hard way. I had a super early departure from DFW one morning, and I was certain that the agent was mistaken about the $400 fee. I paid it, thinking that surely CO would make it right when I brought it to their attention... Nope. Surely this was an oversight on the part of those who restructured the Elite, Premier... whatever they call us anymore. I'll soon be CO Platinum, but there is no break defined anywhere online for even GS. I'm a big fan of this airline, but this leaves an extremely bitter taste in my mouth.
