I'm 17 years old and I will be Flying on my own from Italy to Canada for the first time. I will travel from Italy to Munich and then I will take other flights. I will travel with Lufthansa for all the time and I don't have to change terminals. So, as I arrive at Munich Airport, do I have to follow the "connecting flight" sign? Then what should I do? Sorry, I'm a bit nervous.
Once your first flight lands, and you disembark and enter the airport, there will either be a sign, or an airport employee signalling which direction transit/onward/connecting passengers should go. Follow that and you should enter a part of a terminal where there are gates and one or more TV screens that show which flights correspond to which gates.
Look at your 2nd flight's flight number (either from ticket or boarding pass) and check the TV screens to know which gate your flight will be boarding from. Usually your flight will show up 2 hours before it departs, although some screens may show it even if there is more than 2 hours till it departs.
Once you know the gate number, follow the signs to the gate. Just ask any airport or airline employee if you need directions.
As you follow the signs, you'll be directed upstairs and come to a line and a series of booths for passport control. This is because your flight will be leaving the European Schengen area. Just wait in line until you reach an available booth and present your passport to the officer. There should be a special faster line available for EU citizens (there'll be a sign), which you could use if you're eligible, but someone will direct you if you go to the wrong place.
Once you get to the gate, have a seat and wait until they announce that it is time to board.
Remember: If you ever get lost, or confused, or if you can't find your flight number on the screens, do not hesitate to ask a member of airport staff. They may be tired and grumpy, but they will always help, no matter what. If they can't help, they will at least take you to someone who can.
