But pricing algorithms can be mysterious!

I presumed because the Mexican school holidays are actually almost over by that point, so the rush to Europe will be over. I would imagine they carry a hell of a lot of cargo on that route, so some lightly loaded flights probably just allow them to clear some cargo backlog.

A good point to consider though, thanks for your response. Do you know about changing your seat during online check in once you've made a selection? I now some airlines you can, some you can't, usually once you complete th process and and obtain your boarding pass
