As AB will join oneworld in spring 2012 it's time to think about flying them to get easy status for oneworld. You'll get status + bonus miles for flying with AB and Niki (HG) as follows: Eco Saver 125, intra-europe 250, long distance 25% of flown miles Eco Basic 500, intra europe 1.000, long distance 100% of flown miles Eco Flex 1.000, intra europe 1.500, long distance 150% of flown miles Business 200% of flown miles As Eco Basic and Eco Flex are not that costly it shouldn't be to expensive to collect miles rapidly. Upon reaching 20k statusmiles within 12 months (not fixed to calender year) or 24 segments you'll get Silver Status; with 40k you'll reach Gold. What's quite unique with topbonus: As Gold member you'll get 40% extra miles on all earnings (20% as Silver), flights and other activity included. And you can reserve so called XL seats free of charge (like exit row seats). Also as Silver and Gold you can book companion award tickets for only 50% of the miles. You can also chose one route where you'll get double miles all the time. What I don't like is that miles expire 36 months after earning them if you're not Gold.
