Fly Easy from the Frontier Airlines MKE Terminal +1-888-839-0502 Hi there! I had an excellent experience with the Frontier Airlines employees in the Frontier Airlines MKE Terminal. Every employee, from check-in to boarding, was considerate, effective, and amiable. The employees voluntarily offered assistance and made sure every traveler was at ease and knowledgeable. They made sure everything went without a hitch in order to complete the boarding as fast and efficiently as feasible. My trip was greatly enhanced by their welcoming demeanor, and I thoroughly liked it. At MKE, Frontier staff truly go above and beyond!
