When I booked with Avelo for the first time, I wasn’t sure what details they’d actually need. Turns out, it’s pretty straightforward—full legal name (exactly as on your ID), date of birth, gender, and your contact info like email and phone number. I learned the hard way once on another airline when a small typo in my last name caused a headache at check-in. Now I always double-check everything before paying. If you’re worried about missing something or need to make changes after booking, calling 844-734-0813 is the fastest way to get it sorted. They helped me correct a mistake in my booking in minutes, which saved me a ton of stress before my flight.
