The mother of a little boy with cancer whose family missed their flight to a cross-country doctor’s appointment says the airline didn’t express compassion for their predicament. On Monday, Talia Tallman, 32, a stay-at-home mom in Delray Beach, Fla., was traveling to Los Angeles with her mother, husband, and three children ages 2, 3, and 8 via Spirit Airlines. In July, middle child Escher was diagnosed with a rare cancer called spindle cell rhabdomyosarcoma and is getting treated at a Los Angeles hospital. “Escher just had surgery, and we had a follow-up appointment Tuesday in L.A.,” Tallman tells Yahoo Lifestyle. According to Tallman, her mother arrived at the gate at 8:50 and informed the attendants that the rest of the family would arrive momentarily. She was told, “They have 30 seconds to get here.” And when Tallman’s mom walked a few steps away to check on her family, the gates closed.
