The European Commission on Tuesday gave airlines six months to shape up on passenger rights, or else face legal action. The AFP reports that EU commissioned a study into how closely airlines followed the compensation rules for stranded passengers and found that airlines were badly implementing or bending the rules, which were introduced two years ago. Over the next six months, the Commission will check at airports to see if airlines provide passengers with the information, assistance and compensation required under the rules, the AFP noted. If conditions do not improve, the EU could change the rules to guarantee that passenger rights are upheld.
