Smart ways to pay less

  • Compare two one-ways. One-way from $59 (Wed Oct 28). Two one-ways, even on different airlines, sometimes beat a round-trip. Check both before you book.
  • Check nearby airports. Miami International Airport (MIA) is 47 min from Fort Lauderdale; President Donald J. Trump International Airport (DJT) is 51 min from Fort Lauderdale. Price your trip from each.
  • Count the bags. Frontier's low fare is usually seat-only. Add your bag fees before comparing it with full-service airlines.
  • Be flexible by a few days. These prices are for specific dates. Shifting a day or two, or flying September, is usually the biggest saver.
  • No hidden-city tricks. We never recommend skipping legs of a ticket. It breaks airline rules and can cost you bags, miles, or the return flight.
