💡 Tips for a cheaper ticket

✈️

Flights hackCheck nearby airports

Flying into a secondary airport an hour away can cut the fare by a third; add the bus or train cost before you book.

🗺️

Planning hackSlow down to save

Staying longer in fewer places cuts transport costs and unlocks weekly discounts on stays.

💸

Money hackAlways pay in the local currency

When a card machine offers to charge you in your home currency, say no – the conversion rate is almost always worse.
