There are over-the-top experiences right here in the U.S. as well. America’s Flagship Check-In at ORD, LAX, MIA, and JFK is open to ConciergeKey members. First-class customers on an international or transcontinental flight with three classes, or customers of the Five Star Service—starting at $250 per adult—get a separate entrance to an expedited security line, private staff helping with seat and itinerary changes, updated flight information, and baggage assistance.
