Book your flights in advance.
The earlier you book, the more likely you are to get a good deal.
Be flexible with your travel dates.
If you can, avoid traveling during peak season, when prices are highest.
Consider flying into a smaller airport.
Smaller airports often have lower landing fees, which can translate into lower fares for passengers.
Pack light.
The less you pack, the less you'll have to pay in baggage fees.
Bring a reusable water bottle.
You can fill it up at the airport or at your hotel, saving you money on bottled water.
Eat at local restaurants.
Avoid eating at tourist traps, where the food is often overpriced and not very good.
Use public transportation.
Public transportation is often much cheaper than taxis or rental cars.
Pack a first-aid kit.
A basic first-aid kit can be helpful for treating minor injuries and illnesses.
Take breaks.
Don't try to do too much in one day. Take breaks to rest and recharge.
