We are traveling to Italy in September. We depart the USA on a Lufthansa flight and arrive in Munich with an hour to get our connecting flight to Italy. Are we foolish to think that is enough time? We haven't used the Munich airport in the past.

Changed tag from Italy to Germany.

If they offered that connection then it's technically doable, as long as there are no delays with your flight to MUC. I would check to see if there are later flights to your final destination, just in case you miss this one. Personally, I tend to have very bad luck with short connections. Usually either I miss the connection and/or my luggage does. Just last month, my luggage and I both missed a 2 hour connection in Rome due to a delay coming into Rome. Thankfully they had later flights, but my luggage missed that one too and it arrived the next morning. So in the absence of a later flight, I wouldn't do this.

I just thought of something else. Unless you've been to Europe in the last few months or so, you'll have to register upon arrival. That means going to a kiosk and it takes your picture and fingerprints. We waited in line to do this, but the machines went down so we weren't able to register. I don't know how long that will take, maybe by then the process will be more efficient.

As I mentioned above, you really need to make sure they have a later flight on the same day. Then hope and pray that later flight isn't sold out.

I agree with P_M. I want at least two hours for any layover.
Good luck!

Maybe by September, Germany may offer pre-registration of the EES and an hour *could* be sufficient by then. No way to know just yet.

Munich is not nearly as hectic as Frankfurt, for instance and would feel more comfortable with a shorter connection there. Although in general, l would prefer 90 minutes myself, especially if delays from home airport are prevalent.

With all of that being said, the flight is 4-5 months away and a lot could change before then. You could call the airline and request a later flight (if available) just to be on the safe side. I once had a flight change on me while Europe was in the post-covid meltdown around the 2.5 month out mark. Ironically, was about to call myself given the reports at the time.

They've just canceled a LOT of short haul flights. I'd worry about that more than the connection.

Check and make sure the flight is still flying

Even with pre-registration or having already been through the EES system you are in the same queue for immigration as those who have not.
I would want a lot longer for a transfer, even without the EES problem. Assuming the flights even happen isn't better to have to sit around for a couple of hours and get your connection that be stressed and rushed and miss it surely?
Lufthansa has cancelled many short haul flights until at least October, and will no doubt cancel many more if they need to, as will other other airlines.

Europe currently has just 6 weeks of jet fuel they say.

I have take Lufthansa from Montreal to Gdansk through Munich frequently.
The connection time is 65 minutes and I have always made it with time to spare.

That was pre EES and you probably also have an EU passport as well as a Canadian one.

I can't speak for every airport, but in Rome, the registration was separate from immigration. It wasn't even on the same floor. As soon as we came into the building, they said if you're registered, go straight. If you're not, turn right for the queue to register.

Maybe that is the case in Munich too then, but I still can't see the fun in stressing to deplane, get through immigration and find your gate on such a tight connection.
