Delta on Thursday reported a second-quarter profit of $2.13 billion, up 63% from a year earlier, when the industry was struggling with a glut of open seats on domestic flights. On an adjusted basis, its earnings fell 10% from a year earlier but still outpaced what analysts expected.

There were some rough skies for a couple months there, but Delta seems to think it has now punched through to the other side.

Delta Air Lines CEO Ed Bastian is predicting a “good summer” as the US carrier’s confidence appeared to return with the release of its latest financial results.
