Your American Airlines check in is more than just printing a boarding pass — it’s how the airline confirms you’re taking the flight and assigns your seat. Checking in early gives you enough time to:
✅ Handle any last-minute changes
✅ Pay for extra bags
✅ Go through security without rushing
✅ Deal with unexpected delays
✅ Board calmly and on time
Checking in too late can result in denied boarding, extra fees, or having to rebook altogether — which no traveler wants.
