Transfer time in Munich airport if traveling from US and connecting to a flight to Greece

Either meet the permitted minimums allowed for MUC. Assuming these are connecting flights on the same ticket, and your first flight arrives on time . However, if I had to change terminals, I would feel much more comfortable with the extra time of the 110 minutes. And it's only a 30 min difference. Enough time to stretch your legs after a long flight and maybe get a snack and something to drink. Pretty sure the Passport Control agents are professional in how they treat ALL of the people who pass through their gates, regardless of what passport they hold.

If you are doing this on separate tickets, neither of those intervals are safe.

I have entered both Schengen and the UK numerous times and at different airports since January.

No difference in the way I was treated. In fact, I applied for Easypass in Germany in April and had no problems.

If the airline is offering an 80 minute layover then they believe it is enough time. If for some reason, your flight into MUC is delayed and you miss the connection--assuming it is on the same ticket--LH is required to get you on the next available flight at no cost to you.

First of all, MUC is an incredibly efficient airport, especially when connecting on Lufthansa/Star Alliance flights. 80 minutes is within the minimum connection time, but if your flight is delayed, having the additional time cushion may be worthwhile, especially if the two longhaul flights you're looking at are equally convenient.

One thing to consider is that you may arrive at the T2 Satellite terminal and need to transfer to T2 via an underground shuttle train to catch your connecting flight - it's all well-planned, and doesn't take long, but again, less stress involved with the longer layover.,

Due to flight delays, my flight from US last year arrived in Munich only 20 minutes before my connecting flight to Dubrovnik and I actually made it (although my checked bag not surprisingly did not and came on the next flight). It’s a very efficient airport.

I've flown into MUC at least three times in the last 20 years, and I've always been off the plane, through immigration, and out of the terminal and in the S-Bahn station in less than an hour. So I think getting to another gate in an hour is very possible.

Note: this was before the satellite terminal. It might take a few minutes longer if you have to change buildings.

But note also, I said off of the plane. What if the plane arrives late? I've been an hour late arriving in Germany three times (1/3 of the time).

When coming off an international flight and transferring to a domestic flight I usually allow 3 hours as a rule.. sometimes more sometimes less depending on the airport… while that may sound excessive I’ve never missed a connection for reasons other than a canceled flight and there are numerous things to go wrong. Security backups, screening equipment failures, strikes, incoming flights delayed. In the last 30 years of monthly business travel to Europe I’ve seen just about everything happen.. That said Munich and Frankfurt are both generally efficient airports and my major gripe is usually situations at passport control where there are large backups and only 1 non EU lane open… I would not go less than two hours.. usually I just end up spending the time in an airport lounge..

I would take the short connection the airline offers. Lufhansa offers these connections as a favour to the passenger, because they know people do not like their time wasted. So they have build a terminal in Munich that is designed to make short transfers possible, and they have procedures in place to make this work.
Because it is not in the airline's interest that you miss your connection.

OP is asking about xfer time in Munich, but there are also flight connections in Chicago and
Frankfurt, amongst others.

Everything people say here about Munich does not apply to Frankfurt. Frankfurt is large,
not all that well laid out, and has a habit of parking planes on the tarmac and requiring
passengers to take a bus to get into the terminal for their connections.

So if you end up flying through Frankfurt, pad your connection time a bit.

OP does not say when they plan to travel, but if it's a ways out, know that the airline will
very likely change schedules at some point and potentially make things better or worse.

FInally, note that if you book a legal itinerary/connection on Lufthansa planes and your
final arrival is more than 3 hours late due to airline issues (eg, not weather), you are
entitled to payment under EC261. Not so for UA or AA.

I've actually had quite a few tight connections in the past in FRA. That is why I know that LH does put effort in making sure you make your connection. They know after all who is making connections, which flights are delayed, and which of their customers is at risk of missing a connection.

But I'd connect in MUC over FRA any day, yes. (I do not know how it is to connect in ZRH, as that is where I usually start, but I hear good things about that airport as well...)

keep it simple and less stressful -go with the extra time option. remember - arrival time = wheels down (not gate arrival); departure time = pushback from gate. That 80 mins get quickly cut when everything else is taken into consideration.
