Not sure how exactly to define Low cost/budget airlines but I flew American from Dominican Republic to Miami then on to Montego Bay recently.
I managed breakfast the the airport in the morning. There was not a scrap of food avilable on the first leg of the flight. The "immigration" process in MIA despite being in transit, was so lengthy that I just made the next leg. On that leg again with good ole American, not a scrap of food was available either.
I finally made it to my hotel minutes before room service stopped at midnight and had my first food since breakfast
Not really low cost, certainly not budget, but the lousiest, meanest air journey I ever made by a long shot
