The integration process will be a challenge but I don't think AB is a "classical" LCC like Ryanair or easyJet. AB already works more or less like a network carrier and this may help in the integration process.

Some features:
- AB allows connections and checks your bags through
- AB has a frequent flyer program with other airline partners (S7 among others)
- AB has two classes of services (long-haul)
- AB uses main airports (e.g. FRA,TXL instead of Hahn or Schönfeld), most of which already have a OW lounge
- AB's IT is connected to the ESTA, API databases for US bound passengers
- you can buy AB ticket through consolidators and/or online agencies (e.g. ebookers, expedia.de, etc.)
- you should be able to buy AB tickets through TAs as well (I'm not sure though)
- AB has a limited hub-and-spoke model in TXL & DUS (you can for instance fly from ZRH via DUS to MIA, your bag is checked through, you get boarding passes for the DUS-MIA leg in ZRH, the check-in agent at ZRH enters your API details for the US and checks whether you are ESTA compliant, etc.)


AB is more like B6 in the US which offers you connecting flights, booking via online agencies such as Expedia, etc. They are a low-fare network carrier.
