Today we see the return of a free miles offer we saw in July and November of 2014. Sixt is offering members of airberlin’s topbonus program 1,000 free miles simply for registering on their site for a frequent renter offer from them.
When I signed up for the offer in July I did actually receive the
miles, unlike the similar Miles&More offer which seems many people
did not receive their miles.
To earn the 1,000 bonus topbonus miles simply register online by June 30th.
The registration also offer bonus miles on multiple Sixt rentals, if you
complete 5+ rentals you’ll earn 1,000 miles per rental, 10+ rentals
earn 1,500 while 20+ earns 2,000. The latter two may be tough when the
promotional period is only 30 days long.
