For the Spirit's fans (ough, sounds like a brujeria cult thing...
) I'm sorry but it's not on the poll.
Simply vote on the options and any other non-charter airline you may like that is not on the option, simply make a post.
Some time later in the year I might recreate a new poll on the best airline from N. America and I might include the new options.
Poll options are unchangeable once created.
BTW, if anyone have an idea for a poll, just PM me.
