I recently had to fly from Dublin to Frankfurt on Lufthansa, using an award ticket from United, in Business.
Lufthansa use a shared lounge at Terminal 1 at DUB. My shuttle from the Hilton dropped me at the end of Terminal 2 as otherwise it is a long walk in the rain from the drop-off point to the Terminal. With a short walk I was in to the terminal, and through Fast Track and in to the lounge.
The lift from the ground floor drops you off in the middle of the lounge and you must turn left to check-in, to avoid being shouted at.
The lounge itself was busy when I arrived but it soon emptied out. There are plenty of seats although few sockets so I had to move in order to find one.
The usual cold offerings were there, cereal, muffins, yoghurt, bread, cheese as well as cheeses, juice etc. Both sides of the lounge offer the same fare.
The staff were helpful with lost passengers as well as directing people to their gates. The loos are just outside at the top of the stairs you can use to access the lounge.
A ten minute walk to the gate found that the plane had arrived on stand:
My seat was towards the front of the cabin and had good leg room:
The plane featured the new slimline seats. I find the ones on LH to be more comfortable than those on BA, for whatever reason.
A light meal and drinks were served:
warm rolls were offered also.
On arrival at Frankfurt we were taken to a Schengen gate, although we were a non-Schengen flight and so we all had to disembark from the rear of the plane and squeeze on to the two buses provided. (Except of course, the LH Senator member who got a car ride to his connection, lucky bugger).
After a 10 minute drive around the bowels of FRA, we were dropped off at the terminal, somewhere in the basement of the A gates.
Although I complain about Heathrow, sometimes I do dislike Frankfurt equally.
