Wanted: A frequent flyer program that awards miles for flights on any airline.
That was the nub of a recent query submitted by a reader, voicing a sentiment shared at one time or another by most mileage-collectors.
I responded that no such program exists, and that the very idea of an all-airline frequent flyer program amounted to an oxymoron. After all, mileage programs are in the business of directing loyalty and business to a single airline, or to a group of allied airlines and other partners. A program that allowed members to earn miles on any and all airlines would completely defeat that purpose.
In spite of my best efforts to untangle what is, admittedly, a complicated situation, the piece generated a significant number of responses that suggested I'd overlooked some candidates with legitimate claims to be considered universal programs.
The common thread of those responses was, notwithstanding my contention to the contrary, there are indeed loyalty programs that apply to any airline. Examples given were the American Express Membership Rewards program and the programs associated with various bank-issued cards like the Capital One No Hassle Miles Visa and the Chase Travel Plus Visa.
Are these credit card programs truly the Holy Grail of mileage programs? Absolutely not. But they do have their particular virtues that make them well worth considering, either as adjuncts to airline programs or even, in some cases, as freestanding alternatives.
To reiterate, there is no single program that permits members to freely (important qualifier—see below) earn miles for flights on all airlines. Or even on most airlines. But several credit card programs do award points for charges that can be exchanged for miles in the programs of participating airlines or redeemed for flights on any carrier.
Convertible points from AmEx and Diners
Members of the American Express Membership Rewards and Diners Club Rewards programs earn one point for every dollar charged for most purchases. Those points can then be converted to miles in select airline programs, as follows:
American Express airline partners: AeroMexico, Air Canada, AirTran, ANA, Continental, Delta, El Al, Frontier, Global Pass, Hawaiian, JetBlue, Mexicana, Southwest, Virgin
Diners Club airline partners: Air Canada, Air France, Alaska, American, Asiana, British Airways, Delta, El Al, Frontier, Global Pass, Hawaiian, Icelandair, Korean Air, Mexicana, Midwest, SAS, South African, Southwest, Thai, Virgin
Once converted, the points become true airline miles in the participating programs.
The flexibility afforded by the ability to deposit credit card points into multiple airline programs is an undeniable boon. It's especially helpful for travelers who participate in several airline programs and wish to selectively allocate their credit card earnings among a range of programs.
But, the lists of participating programs fall far short of including all airline programs. And more importantly, they don't even include the majority of the largest U.S. programs.
