Traveling every week by air from NY to Detroit any coupons or special offers? -

I am a frequent traveler, and I would like to know if there are any special offers, or coupons for me to use for one year, since I travel every week to Detroit from NY?I would really like to know since I need to save a lot of money.Thank you

The only thing I can think of is joining your airline s frequent flier program. I m sure you can rack up lots of free points (and free flights) quickly, if you fly weekly.
