Old problem: Allergists have been aware of the potential for serious allergic reactions to peanuts and tree nuts for decades. Along with a general rise in all allergic diseases in the past 20-30 years there has been an increase in serious reactions like anaphylaxis to peanut. It's caught the attention of the media & the public. Since neither people nor peanuts have changed it may be an environmental change.

Allergy testing: Usually you need to be allergy tested both skin prick testing and if negative then confirmed with specific ige test to peanut. If these 2 tests are negative then consider a peanut challenge. However, only about 18% of children will outgrow this allergy (and this is in children who have had very mild symptoms to begin with).

Flying + nut allergy: Most domestic airlines = more likely to follow the following safety measures: have epi pen available; announce that there is a nut allergic traveler on board; have a nut free seating buffer around allergic passenger; no nut containing foods, near nut allergic traveler. But..Bring your own foods, pillow and blanket; have someone wipe down the tray + seat that will be used by nut allergic passenger.
