If you have a business trip, you might want to consider a buffet. Airlines provide these free meals for passengers, and they include dessert and juices in addition to hot food and beverages. The average business trip includes two to three buffet meals each day. Children under three eat free. Airlines also offer wine, beer, and coffee, and the prices are generally affordable. The last seating for the buffet is about 45 minutes before departure. The hours do not apply on holidays or in cases of medical emergencies or mechanical failure.
