    Any way you guys can add Detroit as a departing city to your list, that would help us out a lot?? Thanks

  • Hi @disqus_fnMXtZ0YM6:disqus,

    The coupon code is only valid on dates through December 16 and must be used when booking through the Frontier Airlines website. I attached a screenshot, hopefully this helps. Please let us know if we can further assist you.

    Happy Travels,

    the coupon code didn’t work for me!

    Will you, my friends, let me knwo when there is a good deal to be had from Tampa to Seattle, please? I have not seen my son in 2 years and I am desperate to give that kid a hug.

      Barbara, go to Airfare Watchdog and enter your cities. It will send you updates on fare prices.

        Lynn, I am working on it. Thank you for the hint.

      Barbara: If you go to Frontier’s website, you can book TPA to DEN on Dec 4th to leave at 8:05pm, arrive at 10:10pm. You could then stay overnight and fly from DEN to SEA on Dec 5th, leaving at 7:45am, arriving at 9:45am. Return flights on Dec 14th are: SEA to DEN, leaving at 7:30pm and arriving in DEN at 11:07pm, then leaving 11:59pm from DEN to arrive in TPA at 5:13am on Dec. 15th. This is the best itinerary, though it requires an overnight at DEN airport. But, the airfare is $58 for each leg (minus $5 if using coupon code), which amounts to $232 (or $212 if coupon code works). I don’t know what normal airfares cost from TPA to SEA, but even including a hotel stay, I can’t imagine it would get any cheaper. There are similar itineraries for other dates, but you just have to be creative…remembering that DEN is the key connection point. Good luck!

        Gregg, you are wonderful. Thank you.

          Lol…just very frugal! For future reference, if you ever want to fly to an airline’s hub city and are only using carry-on luggage, it is often cheaper to look for flights to connecting cities in the region (which are often cheaper). If those flights connect in that hub city, you simply jump off and don’t make the connecting flight (make sure there is a plane change, not just a stop-over). For example: If you want to fly to Phoenix, AZ, on USAirways/American, it is often cheaper to book a flight to Los Angeles, which normally connects in PHX. As such, you would need to book outbound and inbound flights separately, but it usually doesn’t affect the overall price. It also provides a non-stop flight instead of possibly connecting in Charlotte, NC and paying a higher fare. There are ways to cut costs, but sometimes they require a lot of research and a lot of patience. Such methods also work best when itineraries are flexible. I hope you are/were able to find what you needed!
