With the help of Jim Tennant of The Tennant Group and Michael Meyer of Rate-Highway Inc., we are conducting rate surveys on a weekly basis and providing analysis and comments where appropriate. We publish this monthly recap in our electronic edition and more comprehensive looks in the print editions.

Including the six city surveys, which has been discontinued, rate quotes have been up in 20 of the last 22 months, but June’s increase was a miniscule $0.14. Therefore, it is heartening to see July’s significant increase of $14.29.

All five regions were up substantially — with the Northwest increasing $32.03, pulling it up over the Northeast, usually the highest of the five regions. A look at the graph shows the average quotes in July 2014 were up substantially over June, but 2013 June and July quotes in all five regions were virtually the same.

As usual, there are large differences between cities. The highest 52-week average quote went to Reagan National Airport in Washington, D.C., at $88.63, while the lowest rate went to San Diego International Airport at $28.52.

The highest quotes in July were at New York’s LaGuardia Airport at $124.60 and the lowest quotes were at Las Vegas’ McCarran International Airport at $30.76, less than one-quarter of LaGuardia’s.
