5 Things to Bring on Every Flight

3. Food
Snacks might not be offered for free anymore, and meals rarely are, so bring something to eat. As a courtesy to fellow passengers, leave smelly foods at home, and, if traveling abroad, be mindful of items like produce and meats that won't be allowed into your destination. Also pack gum or lozenges to head off ear popping during takeoff and landing. Beverages won't make it through security but are often allowed on the plane if purchased in departure areas. Again, check the TSA website for current guidelines and other air travel tips.  

4. Creature comforts
In-flight temperatures drop, and the cabin gets chilly, particularly if you've boarded the plane in tropical-island garb. Pack a sweater, jacket or wrap, and even socks in your carryon to keep warm. Air-travel neck pillows are a nice to have for longer flights.

5. Your credit card
So what if you'd like to have a drink during the flight or you just have to see how that dumb movie turns out? Alas, cold, hard cash is no longer the coin of the 35,000-foot realm. Many airlines now take only credit cards as payment for food, alcohol, entertainment and even Wi-Fi, so get ready to flash your plastic if you want any of these in-flight comforts.
