💡 Tips for a cheaper ticket

✈️
Flights hackCarry-on only

Travel with one cabin bag and you skip baggage fees, check-in queues and the risk of lost luggage.

💸
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.

✈️
Flights hackBook the long-haul as a stopover

Many airlines let you stop in their hub city for a few days at no extra fare – two trips for the price of one.
