A Check-In Counter is a designated area at an airport where passengers go to register for their flight. Here, travelers present their identification and flight information to airline staff. The staff assists with issuing boarding passes and checking in luggage, ensuring that everything is ready for the flight. At the check-in counter, passengers can also ask questions about their flight, such as departure times and gate information. This area is typically located near the entrance of the terminal and is marked with signs displaying the names of various airlines, such as Delta, American Airlines, or United.
