There are between 20-40 low-cost airlines in Europe. Some low-cost airlines are much bigger and popular than others and fly everywhere in Europe, while others are smaller and have a limited choice of flights. All of them share one thing: they made traveling affordable to so many people and now flying between two countries in Europe is almost as easy as taking trains or buses between two cities.
Most major cities in the USA have reliable public transport options to transfer you to the city centres. For example, LAX has a shuttle bus ‘G’ to the Metro Green Line and JFK has the AirTrain connecting to the New York subway. Buses and taxis are also plentiful if you don’t want to negotiate traffic. However, in some cities hiring a car may be the quickest and convenient option to get around especially if you plan on doing a road trip. You’ll find all the major car rental agencies at most US airports, including Budget, Dollar, Hertz and Thrifty.

Before booking a flight, consider if the rate is cheaper if paid in another currency. Often budget airlines will make you pay in the currency of the country you're departing from, but this isn't always the case. An important note when doing this: make sure you're using a credit card that is free of foreign-transaction fees, otherwise your attempts to save money doing this will be lost! Our article on money matters for world travellers can help steer you in the right direction for the best credit cards for travel.
If your country’s currency is currently strong compared to others around the world, search airfare in a country where the currency is weaker. For example, the US dollar is strong and the New Zealand currency is weak. I found a one-way flight from Australia to NYC for $1,000 USD but when I searched on the NZ version of the airline, I found the same ticket for $600 USD. It’s the same airline, same flight, and same booking class. It was just booked in a different currency. This tip does not always work, but it works often enough that it’s something worth trying if your currency is currently doing well.

When it comes to saving money on travel, flying cheap is a must. So forget all those full-frills airlines offering hot meals and oodles of legroom before dropping you off at your destination and look instead to the budget carriers currently criss-crossing the skies of the United States. In fact, there's such a wealth of low-costers in the air today that it's unlikely would-be passengers will find any destination that's not on the roster of at least one, whether its Frontier Airlines of the Rocky Mountains or Southwest, the largest no-frills flier in the world!

Many of these budget airlines have their own airline rewards credit cards, and most of them offer a major signup points bonus. For example, the Southwest Rapid Rewards Plus card from Chase offers 40,000 points after spending just $1,000 in your first three months. However, a general travel rewards credit card such as the Chase Sapphire Preferred is the best option for most people, as you have the flexibility to redeem your points towards a wide variety of airlines and hotels. You'll receive 60,000 bonus points worth $750 through the Chase Ultimate Rewards program after you spend $4,000 in the first 3 months of your account opening, and the card features no foreign transaction fees.
