I had booked a forty minute connection with LH from Dublin through Munich but the second flight has been changed so the connection is now thirty minutes. LH obviously feel they cannot connect that quick so they rerouted me through FRA with a 55 minute connection. I know FRA and it'll be tight timewise clearing both passport and security and then the tunnel from B gates to A gates but I've done it before. Just need to get out of DUB on time. But there is a flight to my final destination an hour after the one I'm scheduled on so it should work out ok.
