Last month, there were initially rumors that United was interested in acquiring the somewhat troubled JetBlue, then Lufthansa. Between 2007 and 2015, Lufthansa already held a stake of up to 18% in the company.
If ever something concrete develops in this direction, JetBlue is likely to become a candidate for the Star Alliance.
While these are currently just rumors, there are also facts: JetBlue has launched a reciprocal Frequent Flyer partnership with another Star partner, TAP Air Portugal. TrueBlue members can thus already earn points on three Star partners, in addition to TAP with Singapore Airlines and South African. Other relevant airline partners in the program include notably Qatar Airways, Etihad, Icelandair and Hawaiian Airlines.
