Thank you all so much. I think I'll gamble on them having half a brain and let it go.
I am not doubting the use of a middle initial ... I don't think that's ever really a problem... well maybe it is if going to the US now.
My middle name is very clearly on the ticket and passport...
My passport says Jane Kodi Smith, my ticket says Kodi Smith
I also can show my drivers licence that says Kodi Smith
Kodi Smith is the name I use. My passport is the only document that lists my full name. Oh and my Ontario Health Card, because they insisted on using my full name against my wishes.
I am going to South America, and won't be travelling through the US at all.
