Hi Micheal, I know you posted a long time ago but I have just joined and noticed that you travel a lot. Maybe you have heard of the Frio bag.This is typically used for insulin but I have been using it and find that it is amazing for Enbrel and comes in different sizes. I bought mine in Toronto but they are originally British and save you worrying about temperature when flying. Hope this helps. They have a web site....Frio,com. Good luck.
