Food and drink: Zero, so bring your own — the guy in our window seat clearly didn't think he was going to get fed when he landed, or he hadn't eaten for several days.
Luggage: Strict 20kg check-in allowance and some hand luggage.
Toilets: One up front, which got a steady stream of traffic throughout the flight.
Airport experience: Berlin domestic is very functional, from the train ride out then a lengthy walk for the check-in through one of the four terminals. There are a number of food, beverage and shopping outlets to take up your time before you board.
Would I fly this airline again? No problem. Newish plane, comfortable and an attractive price.
