Airlines don't come with many perks these days -- in fact, they charge you extra for the basics. However, there are still some things you can indeed get for free.

Some of these items will vary depending on your airline and their availability, so keep in mind: these are general standbys rather than etched-in-stone policies. Here are a few highlights from a list over on Business Insider:
Extra snacks: 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.
A tour of the cockpit: Security measures regulating tours of the cockpit have become stricter, but many airlines will still do it. The best time to ask is usually after a flight has landed, since that's when pilots aren't in a rush.
Basic medications and bandages: 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.
They also mention that free alcohol is often available on long-haul and international flights. It's less common on shorter flights, but it might be worth asking about anyway. I've been on a couple of flights where I've assumed the booze is extra, only to find out it's actually free.
