If you've ever sat next to someone who has requested a vegetarian meal on a plane, you know that these meals are the first to be served. So if you're hoping to get your food before everyone else — which means not having to wait for the full service and being able to get to sleep sooner — request a special meal. There are multiple kinds of meals you can request depending on the airline you're flying, from gluten-free to kosher, so make sure to check online before your flight.
