There's constant frustration with airlines these days, and much of that comes from everything costing way more than a pretty penny.
But if you think nothing is free on planes these days, you'd be wrong. It's just a matter of asking.

Here are 7 things you can get for free on an airline
Airplanes are usually a hub of germs. Flight-crew members do what they can to make sure each flight is clean, but things like tables and armrests get missed. Before you put your laptop or food on a table, ask for sanitizing wipes. Flight attendants usually have them on hand.
A whole can of soda
The flight attendant may cover your small, ice-filled cup with a sweet carbonated drink, but on many flights you can ask for the whole can for your own refills.
Basic first-aid items
If you're on a flight and dealing with a headache or any other minor pain, you can get ibuprofen if you need it by asking a flight attendant. Have a paper cut or minor scratch? Ask for a bandage.
If you're traveling alone with kids and need to step away to the lavatory or stretch your legs, many flight attendants are happy to watch your little ones while you catch a breather.
If there is a surplus of peanuts, pretzels and cookies on the flight, you may be able to get more food to snack on during your flight.
If you're traveling somewhere new and have some questions, your flight staff can usually help. Have a long layover in a city? Ask a flight attendant what the best places are around and in the airport to eat and hang out.
Once upon a time, passengers could go in the cockpit and chat with pilots in-flight. Those days are gone, but you can still talk with the pilot and get a look at the cockpit. Timing matters for this one. It's best to ask to see where the pilots work after a flight if they have downtime, and not before.
All these freebies and extras depend on the flight and airline, but you never know what's available if you don't ask.
