Tell me please which one of the following sentences sounds the most natural and correct?

I am flying to Canada first class.

I am flying to Canada in first class.

I am flying to Canada on first class.

I think that first one is the most and natural, but I have heard people say on first class. By the way, what if I use the word economy, do I say

I am flying to Canada economy

I am flying to Canada in economy


I am flying to Canada on economy?

It's correct to use both first class and economy (and similar descriptions of the level of comfort in travel) with or without the preposition in.

But you would have to rephrase to use on, as in: I am flying on a first class ticket, or I am flying first class on points.

Everybody understands that to fly first class (business class, tourist class etc) means to fly in the section of the aircraft that offers passengers an according level of service, comfort and luxury at a price. To fly first class (or any other class) is a set expression.

To fly in first class means to fly in the first class cabin. Again, the expression is universally understood among travellers although, strangely, it doesn't register on Google Books Ngram Viewer.
