One of the major benefits to online, or Internet, check-in is the ability to make sure the traveler has a spot reserved before arriving at the airport. This allows the traveler to bypass the ticket counter, where waits can be long, especially before popular flights. Usually, this only works out for the traveler if there are no bags to check. In some cases, curbside check-in could take the checked baggage even if the traveler has already utilized the online check-in system; this will depend on the airline.
