If you want to save money, don't go for the food they sell in the airports or on the plane. Not only is it expensive, but it may not taste as good as it looks. Your best bet is to make and bring your own fuel for the long trip ahead...
Make your own cereal mix.
Get a Tupperware or Ziploc bag and fill it up with a healthy cereal brand, muesli and mixed nuts. From there you can add extra bits as you see fit. Dried fruits, like figs, raisins, cranberries and apples all go well together! Bring a little plastic spoon and then ask for milk, and there you go!
Pack a fruit salad that won’t turn to mush.
Mix a bit of firm fruits together - fruits like peaches, plums, apples and cherries.
Prepare a portable breakfast ahead of time.
There is nothing better than homemade breakfast good. Try making blueberry muffins, rosemary scones or even breakfast burritos. They're yummy and easy to devour!
Go with the grain salad.
A grain salad is healthy, filling and it won't wilt like a fresh green salad. Try dressing the salad with olive oil to add a bit of flavour and then shake it up in a container before eating. Add chopped cucumber, tomato, dried cherries, carrots, red onions, cheese.
You don't want to sit in a plane for 12 hours after eating a stodgy meal filled with salt. Try something fresh! Pack a few chopped up veggies, such as celery, carrots, cucumbers, baby corns and broccoli. Pack hummus for a yummy dip.
Pop a bit of popcorn on the stove before you leave and you won't be disappointed. It is a healthy way to fill up and a great source of energy.
Stow an edible souvenir.
When you leave, you'll probably want to take something delicious back with you —and sandwiches are a great portable way to do so, since almost every region has its own signature version. Headed back from South Africa? Pick up a Gatsby. Memphis? A pulled pork slider.
Sweat the small stuff.
Stash some little staples, like plastic utensils and salt and pepper packets, in an easy to reach bag. Other must haves: wet wipes to clean hands and disinfect arm rests and tray tables, as well as a small garbage bag to make passing off refuse to the stewardess quick and easy. And finally, don’t leave home without some common sense: Out of courtesy to your fellow travellers, don’t pack or eat smelly food such as tuna fish, cabbage and boiled eggs.
