This weekend we look at the world’s rudest tourists, examine the possibilities of a USAirways/AA merger and its effect on consumers, and finally, report on a runaway puppy that stopped air traffic at La Guardia.

France wins accolades as world’s rudest tourists

It seems that the ugly American has been replaced with the ugly Frenchman, Russian, Brit, German and Chinese. In a survey, Skyskcanner, a European flight search engine, U.S. travelers seem to have developed a kinder and gentler reputation rather than ugly.

Here are the 10 rudest countries on Skyscanner’s list:

1. France
2. Russia
3. United Kingdom
4. Germany
5. Others
6. China
7. United States
8. Spain
9. Italy
10. Poland

A deal here could work to the advantage of consumers. Keep in mind that on a stand-alone basis, American and especially US Airways lack the scale to excel. A combination would create a powerful competitor to United and Delta for domestic as well as international routes. The new company would provide a counterweight to other huge global airlines such as Lufthansa and Air France. It would be better positioned to compete for emerging-market routes as well. Don’t count it out.

La Guardia flights delayed when dog flees Delta jet and sprints to runway

A runaway dog stopped air traffic at La Guardia. Unable to capture the pooch, the airline brought the owner of the dog onto the runway to get the animal back and on its way.

A puppy took flight at La Guardia Airport yesterday, speeding down a busy runway and dodging planes and a posse of desperate pursuers.

Taxiing airliners ground to a screeching halt, giving their passengers front-row views of the spectacle that at one point saw a frustrated worker get down on his hands and knees in an unsuccessful attempt to convince the 14-month-old Rhodesian ridgeback, named Byrdie, to surrender.

When they finally got back to the plane, workers loaded Byrdie in her crate — and they took no chances. It was shut “with 20 zip ties to triple-check she couldn’t get out, …”
