Upcoming travel from east coast/US to MX: BJX, GDL, CUN maybe others

Would appreciate suggestions for which airlines or points programs I should target to earn for these locations. I expect several trips in the coming year.

Thank you.

I can't speak for the other destinations but Southwest is a great option for flights to CUN.
