Katja, welcome to FlyerTalk. You could try discussing your question with a CO airport supervisor the next time you travel. If you approach the Elite line at the ticket counter, request a supervisor to clarify CO's policy on solo travelers using a wheelchair. I can't imagine that any airline would ask a passenger traveling alone, who has to propel herself in her chair, to wait in long lines. Please post the results of your research, for the benefit of others with the same question.
