Yup, there is an argument. Because they buy planes they should have free reign and do whatever business they like in Germany!!??
This coming from a country that is part of an oil cartel that artificially sets oil prices!!!!!

After all they are buying oil from the cartel and have been for FAR longer than EK has been around!
