“When you got to go, go Frontier Air”. The ( well-worn    ) slogan of the Denver based air carrier might have to be (flushed     ) as the airline announced this week that it would be eliminating ( lavatories        ) on all flights less than two hours long. While not one of the larger airlines, Frontier has (led    ) the industry in cost-cutting measures. The first to eliminate in-flight meals, snacks, refreshment, and movies, they’ve also been charging for luggage for two years and based their seat size on the body outlines of a 12-year-old (  gymnast      ).  The large carriers have all adopted Frontier’s (   previous        ) (efficiencies            ) so we can soon look forward to ( bulging       ) (  bladders      ) on regional flights across the land.  Frontier COO Selga Cheris explained that maintaining (lavatories) on their planes costs the company 4 million dollars a year, and she adds our traditionally seat sizing might actually help passengers to (squeeze         ) their (knees            ) tightly together if they might.
