Free benefits
How to get it: Sign up for rewards plan
This is not the sort of thing Lufthansa advertises, but its previous birthday benefits for Miles & More members have included a free upgrade or complimentary breakfast for an entire stay at Swissôtel locations. Even better, those gifts were valid for a full year. While Lufthansa keeps those birthday benefits a well-guarded secret, they don’t seem out of line with the other perks of the airline’s rewards plan.
