Pros:AirBerlin has always been a lovely little airline. Wonderful crew and pilots all around. A bit more expensive than the low cost carriers, but better flight times and a normal flight experience (or what used to be normal) was their forte.
Cons:What I don't like. They don't know what they want to be. Not the crew or pilots, the executives. In September AirBerlin changed their policy of serving 'free' food on flights. I understand that they are competing with the Low Cost carriers (especially as O'Leary has set his sights squarely on AirBerlin), but charging flights that cost more than double of a low cost, yet offering the same experience of a low cost is a sure way to lose customers. Case and point: Flight to Vienna, we were offered complimentary sandwiches and drinks. Return flight, they charged for drinks and food. Which is it, AirBerlin? Either do complimentary food and drinks and keep your customers or keep you fares the same, charge for drinks and food and lose customers. But doing both with no rhyme or reason shows that those in charge do not understand their business.
