NEW YORK (AP) — More travelers will take to the skies this summer, the U.S. airlines’ trade and lobby group predicted Thursday.

About 210 million passengers — or 2.28 million a day— are expected to fly on U.S. carriers between June 1 and Aug. 31. That’s up 1.5 percent from last summer and the highest level in six years, according to the trade and lobbying group, Airlines for America. U.S. carriers are increasing the available seat miles they fly by 4.5 percent.
