Something like Jet Blue in the US?
Not a full code share nor close relationship. EI are offering services via WJ in YYZ but WJ are not offering EI flights via their website. More like Flybe set up.
Interesting development as BA and WestJet terminated their code share agreement last year.
I did notice that but AA are still with WJ while both AA and BA dropped JetBlue not so long ago.
EI need us partners for their business model to work. Perhaps WJ will be more acceptable than AC whenever OW happens.
