Delta flight attendant medical and drug testing: the pre employment physical, random testing and what actually disqualifies at a US carrier

Delta, and the medical threads are all EASA and the Gulf, which are strict and formal. The US is different, and the drug testing side is the part that surprises international readers and even some Americans. Here is how it works at a US major, Delta specifically.

The pre employment physical

After the conditional offer, a physical at a company designated clinic: vision (corrected is fine), hearing (a basic screen), a general exam, and a review of the medical questionnaire. It is less formal than the EASA cabin crew medical and far less than a pilot medical. Most people pass. The things that can be an issue are conditions that would prevent you from performing the safety functions, and those are discussed individually, not automatically disqualifying.

The drug test

This is the part. US airlines operate under federal DOT regulations for safety sensitive employees, and flight attendants are safety sensitive. That means a pre employment drug test (a urine test for the standard panel including marijuana), random testing throughout your career, post accident testing, and reasonable suspicion testing. A positive test at pre employment ends the offer. A positive random test ends the career, with a return to duty process that is long and rarely used.

Marijuana specifically

Legal in many US states. Illegal under federal law, and the DOT test does not care about the state. Crew from states where it is legal are caught by this regularly, and a positive test is a positive test. If you are applying to a US carrier, stop well before the application, because the detection window for regular users is weeks. This is the single most common way an American loses a flight attendant offer and nobody warns them.

Alcohol

The DOT alcohol rules: no alcohol within the pre duty window (eight hours at the federal minimum, often more at the airline), a blood alcohol limit at reporting that is close to zero, and testing when there is suspicion. The airlines enforce it. The layover threads on this forum about alcohol are relevant.

Prescription medications

Some are fine, some need to be declared, and a few (certain sedatives, certain ADHD medications) need a review because they can affect the safety functions. Declare everything on the questionnaire. An undeclared medication that shows up in a test is treated as a positive.

Random testing in practice

A notification at sign on or at the end of a trip, a walk to the clinic, a sample, back to the day. It happens a few times over a career. It is routine and it is not personal.

For international readers

The US system is medically relaxed and pharmacologically strict. The EASA system is medically strict and does not random test. Different philosophies. If you are joining a US carrier from abroad, the drug testing is the thing to understand.
