mid Aug to mid Nov is the 3 month period and my flights are 2nd Nov & 16th Nov DUS-CUR (books about a week ago).
I am also sceptical that €150m will last three full months. I guess I’ll just have to wait and see.

If cancelled I’m wondering if TopBonus will reinstate my points. I don’t expect so but it depends how TopBonus actually pays AirBerlin; in terms of how and at what time / date. TopBonus may actually still have my points, not AirBerlin (or the cash value they’d pay AirBerlin).
The other complication I have (and others I expect) is that IF points are reimbursed, how will they be treated if they are reinstated after the expiration date of the original points !!
ANY IDEA IF THE TRANSFR OF POINTS BETWEEN TOPBONUS AND AIRBERLIN CAN BE STOPPED ????????

Those who have paid in cash might be in a slightly better position if flights are cancelled as whilst AB won’t give you a penny you might find credit card or travel insurance will compensate you.
The issue with using points which complicates my booking is that it’s nothing to do with a credit card and I expect most (if not all) travel insurance companies won’t cover loss of points.
Therefore if I do manage to get Credit Card to refund me or Travel Insurance compensation it would only be for the taxes & fees paid (about £400) and not the true value of two business class flights to Curacao

There goes my gift to my Mum for her 70th Birthday of 2weeks in Curacao :-(
