Two-year-old Causes Allegiant Flight Delay CheapOair Staff August 2, 2011 general No Babies On-board This Time The terrible twos were in full-effect Saturday when a two-year old was running around in the cabin causing the Allegiant flight to delay. With no car seat to be held down the toddler wouldn’t stay in the airline seat either. The pilot would not let the toddler have his way anymore and requested the youngster and two guardians be removed from the flight. For what was to be a 2:10 departure flight, it didn’t leave until 3:10. According to the MSNBC report, the two-year-old and guardians were placed on a Sunday flight. They were told to have a car seat.
