My family of four were denied boarding on Vueling flight VY6864 from Florence to Catania on August 3, 2018. I filed a claim for 1,151 Euro (250 per passenger plus ancillary expenses) with the airline on August 18, 2018. I have provided written documentation and received a customer service claim number. I have followed up on the claim several times and sent the documentation to company officers noted on the Elliott website. The only responses received have been "auto" responses to my emails and a phone call (from a live Vueling employee, no less!) stating that my claim is being reviewed. We incurred expenses of 2,400 Euro to rebook our own flights to Catania, so I am unwilling to give up on this matter. What other avenues are there? Should I file a complaint with the Italian civil aviation authority? Any advice is appreciated.
