Customs is actually what will define how much time you will have to spend at the airport upon arrival.
When you arrive in Los Cabos, the airport staff will put you through a random process that consists of pressing a button, if the light goes green you are free to leave, and if it goes red your luggage will have to go through a check.
Although it is a process that you can not get rid of, just keep calm and patience and you will see that all this time at the airport will pass faster than you expect and you can finally enjoy a quality time in a dream destination
