The picture says it all - unhappy crews again. This week it was Lufthansa, who knows which airline is next. Brett Snyder, airline blogger at Crankyflier, explains that while this week was Lufthansa's crews, there has been a lot of airline labor unrest across the EU. Moreover, another big strike is threatened at British Airways - again.

Air Travelers must be growing increasingly frustrated with the labor unrest. After all, air travel has become so crucial to business that disruptions play significant impacts in an economy as a whole. No developed economy can survive a long aviation system strike without the disruptions affecting most of the economy. Labor knows this and is trying to roll the dice for better pay and protection. It may be a bet they lose in the long term. Because just as travel has become global, so has the industry. Airline managers have options they did not have before. But in the meantime the traveler has to deal with all sorts of disruption planning.
