Someone started a new Facebook group titled "Bicyclist Boycotting Delta Airlines" after learning from Delta that they charge US $200 for a bicycle, EVEN a folding bicycle in a standard suitcase. He posts the e-mail he got from Delta which states that all bikes including folding bikes are subject to the fee. Regardless of the folder rule, $200 for a bike is absurd. If you've got a Facebook account, you might want to consider joining this group. I posted this on the Folding Bikes forum, as well.
