Improper maintenance
    We were anticipating an hour and a half flight.They told us not to use the bathrooms on the plane as we were because the water had frozen in the tanks and was improperly drained.
    Full Fright
    We all boarded the plane and in about a half hour later they had us all get off the plane because they said that they could not fly due to regulations with the bathrooms and that they have to be running correctly to fly. We found out when we got back on the plane that we were unable to use the bathroom anyway and this whole process took over an hour and a half and we missed our connecting flight by 20 minutes and they would not hold our plane. If they wouldn't have screwed around we would have been able to catch our flight on time.Now we will get home 24 hours later than expected.
Frontier Failures
 Air crew forced us to violate FAA’s on-board regulations! 


 But Frontier has LIED, telling AMEX we flew all four segments which is an absolute lie! 


 ...we were short a stewardess for our flight and we had to wait for them to arrive from another city...Completely unacceptable. 


 This airline is an absolute joke, they nickel and dime you for everything, there is no customer service, and apparently the idea of a flight going as planned is impossible. With the arrival of United and Delta to our area never again will I fly with Frontier 


 This airline is awful. They nickel and dime you, they are rude and unorganized. I will never fly this airline again...EVER
