1. The entire can of soda
Flight attendants generally dole out half 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.
2. Hot chocolate
As an alternative to coffee or tea, most airlines also offer hot chocolate.
Etihad Airways and Southwest Airlines are two that offer hot chocolate in economy. Qantas even has hot chocolate made with Cadbury chocolates to satisfy your sweet tooth.
3. Temporary babysitting
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 disembarking.
4. Sanitizing wipes
Airplanes are dirty and carry a lot of germs, which is why you want to wipe down surfaces like the tray table 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.
5. Grooming kits
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 free amenity kits on economy, while Etihad's complimentary amenity kits on longer flights include socks, a toothbrush, toothpaste, and earplugs.
