I also carry a epi-pen for a peanut allergy. I haven't flew in 2 years but the first time I flew, They questioned it among theirself, nothing was said to me.
One of the attendents knew what it was an pushed it through, the last time we flew about 2 yrs ago, nothing was said at all. From what I have heard this time around, it must be in the original box with the patients name on it, you can also get a letter from the Dr. saying you must carry it with you at all times. I haven't heard of any problems with the pen and flying.
I haven't flew because of the fear of flying and the peanut allergy, I was new to it so I never thought twice about it. I have heard about washing everything down. I talked to the Dr. and they say just be prepared with everything, the chances are more touch contact then ingest contact, is what I was told.
The last time we flew though was with Southwest, my DS vomited the whole time, once we got there he was fine, so I am worried was it air sickness, or peanut allergen?
We took the first flight out and I really don't remember what was served. We drove home so I can't compare to the flight up.
That was his 2nd time flying, the first time was with Spirit we flew up and back, with no problems.
Next Year we are flying, I will be calling the airline and wiping everything down, nothing is to exetreme when it comes to PA.
