10 things you should ask for on your next flight

Flight attendants generally dole out half of a can, which, combined with the quantity of ice they dispense, simply isn't enough to quench our thirst.

Next time, order a whole can. Flight attendants are often happy to oblige, or, if they've run out of cans, they'll be happy to return to refill your cup.

As an alternative to coffee or tea, most airlines also offer hot chocolate.

Etihad Airways and Southwest Airlines are just some of the airlines that offer hot chocolate in Economy. Qantas even has hot chocolate made with Cadbury chocolates to satisfy your sweet tooth.

For parents traveling with children, it’s great to have a helping hand when you need to step away for a few minutes. Many flight attendants will be happy to briefly assist you with your kids.

Etihad Airways offers "Flying Nannies", who can organize everything from arts and crafts to hand puppet games and magic tricks for kids, while Gulf Air has its "Sky Nanny", who can assist you with boarding and disembarkation.

Airplanes are dirty and carry a lot of germs, which is why you want to wipe down surfaces like the tray table in order to avoid getting a cold.

If you forget to pack your own sanitizing wipes, ask a flight attendant since they usually have them on hand.

On longer flights, some airlines tend to stock items like earplugs, pens, combs, and playing cards that they're happy to give away.

Virgin Atlantic gives away free amenity kits on economy, while Etihad's complimentary amenity kits on longer flights include socks, a toothbrush, toothpaste, and earplugs.

The complimentary snacks offered on flights are tiny and often leave you hungry.

Simply ask for seconds — if there are leftovers after all customers have been served, flight attendants will happily give you an extra snack.

Since airlines are basically charging passengers for everything these days, most assume this applies to alcoholic beverages as well. However, many airlines do still offer free booze.

Lufthansa offers a selection of free champagne, wine, and beer on its flights, while Finnair has complimentary beer and wine. Etihad also offers passengers a complimentary bar service, with a range of beers, wines, and spirits to choose from.

While it depends on the airline's regulations, most flights are equipped with basic medications like painkillers and antacids, as well as Band-Aids. These are free if you ask.

While wing pins, which are small plastic wings with an airline’s logo, seemed like they had become an amenity of the past, some airlines like Delta still offer them on flights.

Forbes recently reported that American Airlines brought kids’ wings back, starting with flights from Charlotte to Orlando where kids often travel to destinations like Disney World and SeaWorld.

Whether you're in need of more water or want to avoid drinking water on an airplane unless it is bottled, airlines will usually have small bottles of water on hand that they can supply to passengers who ask for them.
