Carla (Rhea Perlman) wants to visit Eddie out of town, but she's afraid to fly. Frasier (Kelsey Grammer) invites Carla to join his fear-of-flying therapy group on a plane trip (to Seattle, of all places!). Need it be added that a disaster ensues wherein both Frasier and Carla wonder if they'll ever return alive. Back on terra firma, Cheers receives so glowing a revue from a tough restaurant critic that everyone is convinced that Rebecca (Kirstie Alley) slept with the man. ~ Hal Erickson, Rovi
