Last month, I had an early morning Delta flight and wasn’t sure when to check in. I learned that Delta allows online check-in up to 24 hours before departure, which was perfect for me to select my seat and avoid airport lines. When I needed to tweak my booking last minute, calling 877-297-0699 was a lifesaver—they quickly helped me modify my flight without any hassle. Showing up at the airport already checked in made everything so much smoother, and I even had time for a quick coffee before boarding. If you like being prepared and stress-free, I’d definitely recommend checking in online as soon as it opens, and keeping that number handy in case plans change unexpectedly.
