This is crazy. Why do we have EU directives and passenger rights if airlines can so easily ignore them? There has to be a way to escalate and force them to do the right thing.
I am, of course, a frequent A3 flyer, and I will most definitely use my vouchers, but this is a matter of principle and to stand up to those who may not be able to use the vouchers. No airline should be allowed to get away with this.
