Delta flight attendants must be at least 21 years old and have at least a high school diploma or GED. But they do prefer high education. Attendants are expected to be willing to work a flexible schedule and be fluent in English (speaking, reading & writing).

In 2026, airlines do not typically require a specific GPA or "A-student" grades to hire you as a flight attendant. The minimum educational requirement is almost universally a High School Diploma or GED (or a "10+2" qualification in countries like India). Recruiters prioritize soft skills and personality over academic excellence. They look for "B" and "C" students who excelled in communications or drama just as much as "A" students. What matters more is a clean background check, fluency in English, and—most importantly—documented experience in customer service, hospitality, or safety. If you are a college graduate, it can give you an edge, but your "grades" are far less important than your ability to remain calm in an emergency, your physical stamina to stand for 10 hours, and your "Warrior Spirit" for teamwork. As long as you have your diploma, your interview performance and grooming will be the deciding factors.
