Hi. First I hope you enjoy your trip. My mom and I are going to have a fun day in Las Vegas never been if I get well. Anyhow I have flown more times with rsd then without due to my rsd and needing to get to the location. A few thoughts I have and I have rsd in legs and possibly eyes/ear. Anyhow I always get a wheel chair to and from the gate. The walk would be too long and painful and then they allow you to board first anyhow usually or you can tell them. Standing in the line pre hand is not good. I usually fly alone so I get an aisle seat because some people don't like to get up if you need to use the restroom and I don't want any accidents on my leg. On that note you should wait till all get off cause it is very close and I learned this almost getting hit by accident. It would of been a bump but to my rsd leg it may as well of been a bat as you know I am sure. I too get cold so bring layers. Try to not get to nervous. Since I have this in my eyes and ears I also get nervous but the anxiety makes it worse. It is just a long day but not so bad and I try to focus on getting to my goal and knowing I did it and you too. Try to get up and go to the bathroom even if you don't have to just to prevent cramping. Ok sending many safe and happy wishes for an amazing time.
