I’ve flown Air Berlin several times now, and I have to admit the airline confuses me. Its prices are often excellent, especially if you book during a sale (offerings such as 2-for-1 tickets can often be found on their website). The website is functional, allowing smooth and easy purchases and online check-in. On board, passengers are treated to free drinks, snacks, and magazines, even on very short flights. No luggage charges. Seating is assigned (you can choose your preferred seat when you check in online), and no one has ever hassled me about the size or weight of my carry-on. Basically, it’s everything the full-service airlines used to be, before they all turned into fee-grubbing customer-hating cesspools.

So what’s the catch?
So far I haven’t been able to find one. I’ve even called their customer-service hotline, only to find it staffed with competent, friendly people who demonstrated problem-solving skills. Sure, there are a couple small, nit-picky things I could mention (a small fee for using a credit card on the website, for example), but given the state of most other airlines these days, they hardly seem to matter.
Air Berlin flies from a ton of German cities to destinations all over Europe, plus a few farther-flung places (such as New York and Phuket).
What’s your experience with Air Berlin? Are any other airlines (low-cost or otherwise) worthy of praise these days?
