It is standard practice when issuing a press release to have both parties agree to the wording before it is released. It is also standard practice to have quotes from management at both parties in the press release. Unless Oxford just made up the Jet 2 quotes, I'd say the terminology was agreed by Jet 2, as they certainly made input in the press release.
I haven't seen Oxford saying Jet 2 are planning to take anyone soon and they haven't added any to their jobs report, so it sounds a bit like a chip is on someone's shoulder here to me. Only time will tell what it really means, so we might just have to wait and see what happens when Jet 2 needs more pilots unless someone's seen the contract.
