The NTA incorporates some advantages, such as the ability to check the luggage over two hours in advance and not have to worry about your belongings during the day of departure (ideal for charter airlines). So you can spend your time like you want without the need to be 2 hours before your flight to check in your luggage (only 40 min for example to pass the control).
Look between the seconds 44 and 52. This is the luggage warehouse with more than two hours in advance. I apologize for being in Valenciano (like Catalan). If I can I put subtitles in English.
