American Airlines first quarter earnings fell year-over-year by about three-fifths, down to $234 million. It’s fair to say that despite disappointing credit card signups impacting revenue forecasts in Q1 the AAdvantage program really did earn the bulk of the airline’s profits.
Indeed, though they do not break out numbers this way, it’s possible that in the first quarter AAdvantage earned all of the airline’s profit and without selling miles the airline itself would have operated at a loss. And that’s even before unilaterally announcing employee raises which financial analysts grilled the airline over.
