New technology can make life a lot easier.
Registering online is probably the best way to save time at the airport. By registering online, which you can normally do it 24 hours before your flight, you will receive your boarding pass by e-mail or text message. There are also machines at the airport that will print your boarding pass without having to go in line. You will not have to go to the airline counter if you do not check baggage. Otherwise, all you have to do is go to the baggage counter.
Another advantage is that several companies allow you to select a seat free of charge only from registration. Whether you are more of the porthole or aisle type, it’s time to choose your place among those that have not already been booked by those who have paid.
