If you plan on flying Spirit Airlines or Allegiant Air, either bring your own food onboard or eat before you get there.
“Not too much in terms of healthy options,” at Spirit Airlines, said Charles Platkin of dietdetective.com, which asks major carriers to hand over nutritional data for their onboard fare, and then rates the airlines’ choices.
Both Spirit and Allegiant scored measly grades of 1¹/₂ out of five stars, bringing up the rear among the dozen airlines surveyed.
