DALLAS (AP) — A new report suggests airlines are flying into a cloud bank when it comes to quality.

The report by a pair of university researchers who track the airline business says more flights are late, more bags are getting lost, and customers are lodging more complaints.

Dean Headley, a marketing professor at Wichita State and one of the co-authors, says passengers already know that air travel is getting worse and now the numbers bear them out.

For example, on-time arrival fell to 76.2 percent last year from 78.4 percent in 2013, while the rate of lost, stolen or delayed bags rose 13 percent in 2014.

Consumer complaints jumped 22 percent in 2014 with many of the worst marks going to regional carriers such as American Eagle, United Express and Delta Connection.

On-time performance also fell and complaint rates rose at American, United, Delta and Southwest.
