Frontier is adding new nonstop service to/from Denver (DEN). New flights from/to Baltimore (BWI), Hartford (BDL), and Fort Lauderdale (FLL) will begin in March 2019. Intro fares are as low as $97 roundtrip for purchase through tonight.
New Frontier Service: Denver to/from Baltimore, Hartford, and Ft. Lauderdale
All of these new routes begin service in March 2019 and will be offered on different days of the week. Frontier hasn't flown to Hartford since 2011 and Baltimore will be a brand new city for the airline. The Ft. Lauderdale flights will be in addition to Frontier's existing service between Denver and Miami, providing even more competition on this popular route.
Intro fares are available from the start of service through May 21, 2019. I've included the start date and days of the week each route will operate. However, the lowest fares are available for travel on Tuesdays, Wednesdays, or Saturdays, and must be booked by December 19, 2018.

Keep in mind that Frontier charges extra for any bags larger than a small personal item (small backpack, large purse, etc.). Pack super light to get the lowest price. Checked bag fees start at $25-$30 each way. Larger carry-on bag fees start at $30-$35 each way.

Look for other airlines to lower airfares with the added competition. Baltimore and Ft. Lauderdale won't see much difference since Spirit already flies those routes with the ultra-low-cost model, but Hartford should see some pretty nice price drops to the west coast.
