Frontier is focused on more than low fares. The carrier offers customers the ability to customize travel to their needs and budget. For example, customers can purchase options a la carte or in one low-priced bundle called the WORKS. This bundle includes refundability, a carry-on bag, a checked bag, the best available seat, waived change fees, and priority boarding.

The airline’s frequent flier program, FRONTIER Miles, lets members enjoy many benefits as well as the ability to attain Elite status. Like the airline, FRONTIER Miles is family friendly, and the program makes it easy for families to enjoy the rewards together, including family pooling of miles. FRONTIER Miles is aptly named because you earn one mile for every mile flown – no funny formulas at Frontier. Whether customers travel a little or a lot, they will find FRONTIER Miles rewarding.

Frontier has been an industry leader in healthy travel initiatives and is currently the only U.S. airline conducting temperature screenings for all passengers and crew prior to boarding. Anyone with a temperature of 100.4 degrees Fahrenheit or higher will be denied boarding as a step to better protect other passengers while flying.

Additionally, in April, Frontier announced sweeping health and safety enhancements affecting every step of a customer’s travel journey with the airline. Beginning with required face coverings that must be worn by all passengers and team members throughout every flight and a health acknowledgement. Prior to completing check-in via the company’s website or mobile app, passengers are required to confirm that:

  • Neither they nor anyone in their household has exhibited Covid-19 related symptoms in the last 14 days
  • They will wash their hands/sanitize before boarding the flight
  • They understand and acknowledge the airline’s face covering policy and pre-boarding temperature screening policies

Frontier also introduced a fogging disinfectant to its already stringent aircraft cleaning and sanitation protocols, which provides a safe, certified disinfecting solution proven to be effective against viruses. The fogging includes virtually every surface in the passenger cabin. Planes are wiped down every night with additional disinfectant, as well.

During flight, main cabin air is a mix of fresh air drawn from outside and air that has been passed through an air filtration system that features HEPA filters capable of capturing respiratory virus particles at more than 99.9% efficiency – similar to those used in hospital environments. Frontier’s modern all-Airbus fleet is among the youngest in the world – all aircraft currently in operation are less than four years old.
