The club statement didn't mention it as far as I can see (unless I've skipped over it). It was the HDM article that stated it was our biggest ever sponsorship.
They've also just expanded into the UK, Germany and Switzerland and they have that Dutch company as well. I mean it's a hell of a deal for us, especially as we're not even a PL club.[/QUOTE
The official statement did say that, extract from the official announcement off the club Facebook page below (wasn't sure how to link the actual page).
We are excited to announce Corendon Airlines as our new front-of-shirt sponsors in a club-record Championship sponsorship deal.

Irrespective of their expansion plans they're a pretty small budget airline operating in a very tough market, so to commit to a multi year 8 figure sponsorship deal with a Championship club doesn't make a lot of financial sense (Turkish link or not). Thus if true there's got to be a lot more to this deal than we know about at the moment. Interesting times.
