It's not you. But everyone else. The ones with more than one bag. The ones with liquids, creams in their carry-ons that they have carried from their origins which they are allowed to and then they realise they have to ditch their make-up, creams, medicinal liquids etc. It's those people who will be holding you up. There will be tears, arguements, people who don't want to throw their things away, or they will be there holding up people while they repack their bags to recheck in . They will be there about a hundred or so, AHEAD of you. And you can't say to the security staff that you're going to be late for a flight. Why are you so important ahead of the other people?

75 mins. Say your flight gets in on time. You taxi to your gate. Oh, wait there's a plane on the tarmac blocking your plane from parking. Wait another 10 mins.

You get to gate. LH parks at the furthest point from T2. You need to trek for at least 10 mins to Connections Centre. You go through security there. Then you go to Terminal 3 presumably you will have your boarding passes already. Then at T3, you will be subjected to ANOTHER security check for people going on US flights.

That's the worst scenario. But it's better to be prepared right?
