Dallas-based Southwest had fuller planes, too, with load factors at 84.5 percent, up 1.8 points from the same month in 2014.
The load factor is calculated by taking the revenue passengers carried multiplied by miles traveled and divided by the total available seat miles.
The average Southwest flight was 988 miles in March, up .9 percent from March, 2014. The total amount of trips flown decreased 2 percent.
Southwest also released its first-quarter traffic results.
The load factor for the first quarter was 80.1 percent, up .8 points from the first quarter of 2014.
The airline carried 5.5 percent more revenue passengers, had its revenue passenger miles increase 7 percent and total capacity miles jump by 6 percent.
That includes the launch of new flights to San Francisco and Oakland from Dallas Love Field.
