-Hello sir!
-hello madam, how can I help you?
-Well... I got my boarding pass and this is my first time here. I have no idea what to do.
-You must go right there and you have to wait for those guys check your luggage. After the luggage îs checked, go at that woman and show her your tickets. She'll let you go board the plane and then, take your seat. Finally, you can enjoy your fight.
-thank you so much!
