I fly regularly as Robyn and have never had any big problems. I do get questioned at times if this is the correct ID and I just tell them yes I am trans. Most of the times they seem relived. I have flown so much now that it I look forward to what will happen. The TSA agents have seen almost everything so they are real cool with it once they feel confident that you are who your ID says you are. I don't get offended if they don't recognize me from my ID, it really is a compliment if they have a hard time figuring it out. They have a hard job to do but most really do try to be polite and respectful.
