United Airlines has teamed up with Mercedes Benz to offer high-value frequent fliers chauffeured rides from the tarmac to connecting flights.
With Delta, the chauffeured cars that pick up premier travelers are Porsches.
Not to be outdone, American Airlines announced it has teamed up with Cadillac, starting at Los Angeles International Airport, to offer similar gate-to-gate service.
As part of the partnership, Cadillac will soon offer frequent flier members points for test-driving Cadillacs.
By the end of this year, American plans to roll out the chauffeur service at Dallas-Ft. Worth International Airport, New York's LaGuardia Airport and John F. Kennedy International Airport.
Don't be surprised if you don't see a Cadillac waiting for you when you get off your American Airlines flight. The service is reserved for ConciergeKey club members, which is an invitation-only program for influential, big-spending travelers.
"It's not a request service," said Suzanne Rubin, president of AAdvantage loyalty program. "It's a high-touch service for those incredibly valuable passengers."
