1.Passengers arriving at an airport for departure must first wait to check in to obtain a boarding pass and check their luggage. Then they must pass through the airport security. Those passengers that passed through security proceed to the gate. At the gate, the passengers must wait for their row to be called to have their boarding pass authenticated. If the boarding pass does not match the departing flight, the passenger is directed to the appropriate gate. The passengers that have an excessively large bag as carry-on must first wait for an attendant, and then, they
are directed back to“check in” to check the luggage piece. Subsequently, they must pass through the security again to return to the gate. Passengers with the proper boarding pass and appropriate size carry-on are allowed to enter the jet way and board the plane.

process.
(ii) How might this process be improved to avoid delays?
