@gooddream, those repetitive ads often tire, but I think they are necessary for those who make a plane trip for the first time. There are unusual things that happen at airports. How can they check a ticket so many times and not realize you're on the wrong flight? What a way to manage security. Something unthinkable has happened to me, the manual revision of the suitcases due to faults in the laser beam system or the lack of electricity at the airport. Can you imagine all the clothes and personal garments in public view? Well, nothing is perfect in this world. Greetings, friend, a hug.
