Their fleet comprises of Boeing and Airbus. Plenty other companies with that mix. As for having several variants within the generic type, that doesn't add so much more to the overall operating costs. It does however give much more flexibility. I just hope they don't go the RYR direction regarding their service product. I fly BER and I hope they won't deviate too much from their current product. I think that their main problem lies in their fragmented route network and bases. This is obviously what they intend to address.
