– Call the airline in advance to learn its policy on food allergy and what snacks are served, and about special seating arrangements.

     – Confirm your food allergy status with the gate agents and flight crew.

     – Pack safe snacks; most airlines allow fluid exceptions for formula and breast milk.

     – To head off hassles, bring a doctor’s letter regarding these fluids and also about carrying an epi-pen.

     – Label your carry-on bag clearly so in the event of emergent need for your epi-pen or medicine, you can locate it quickly.
