Today we see the return of a free miles offer we saw earlier this year (see our post from July) 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 we 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 December 31st.
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 38 days long.
