Find Cheap Flights to the United States and Compare Economical Plane Tickets

Winter is the low season for most cities, ideal for finding cheap flights to the United States and avoiding large crowds, except during the Christmas holidays.

Spring offers mild temperatures and is an excellent shoulder season to visit. Prices for cheap flights to the United States begin to rise, but there are still good deals.

Summer is the high season, with higher prices due to school holidays. It is the best time to visit national parks and coastal areas, although you must book in advance.

Autumn is one of the best times to visit, with pleasant weather and falling prices after the summer peak. Look for US flight deals before Thanksgiving.

Spanish citizens generally do not need a traditional visa for stays of up to 90 days for tourism or business. However, they must obtain an electronic travel authorization known as ESTA (Electronic System for Travel Authorization). It is crucial to apply for ESTA at least 72 hours before your **flight to the United States**, although it is recommended to do so as soon as you book your economical USA plane ticket. The process is online and has a cost. Make sure your passport is valid for at least six months after your planned departure date from the US. Having an approved ESTA does not guarantee entry, as the final decision is made by the customs officer. Always carry copies of your itinerary, proof of sufficient funds, and details of your accommodation to avoid problems upon arrival. Planning is key to ensuring a smooth trip.

Given the vast extent of the US, internal transportation varies greatly. For long distances, domestic flights are the fastest option, especially if traveling between cities like New York, Los Angeles, or Chicago. Consider booking **cheap Los Angeles flights** or **cheap Chicago flights** in advance to save money. Car rental is almost essential outside major metropolises like New York, Boston, or San Francisco, where public transport (subway, buses) is efficient. In rural areas, you will depend on the car. Keep in mind that traffic rules and distances are much greater than in Spain. Highways often have electronic tolls, and traffic fines are high. If you are looking for **cheap flights to the United States for families**, the car offers greater flexibility.

Accommodation in the US offers a wide range, from budget hotels to luxury apartments. In tourist cities like Orlando Disney or the Las Vegas Strip, book well in advance, especially if you are looking for **cheap flights to the United States for families**. A key cultural aspect is tipping (tip). Unlike in Spain, where tipping is optional, in the US it is mandatory and constitutes a significant part of the service workers' salary. It is expected to leave between 15% and 20% in restaurants, taxis, and beauty services. Not tipping is seen as disrespectful. Furthermore, the prices shown in stores and menus do not include taxes, which are added when paying, which can surprise Spanish travelers. Planning your budget with this in mind is a good **tip for finding cheap USA flights**.

The United States is generally safe, but safety varies greatly depending on the city and neighborhood. In large urban centers like New York or San Francisco, stay alert in crowded tourist areas and avoid displaying valuables. It is vital to have comprehensive travel insurance, as medical care is extremely expensive and not comparable to Spanish public health care. To avoid looking like a tourist, try to use public transport when possible instead of constant taxis and explore less central neighborhoods. Remember that laws regarding alcohol and tobacco are strict and vary by state, especially the legal drinking age, which is 21. A good tip from TICKETS.COM.ES is to visit a local market in cities like Seattle or Boston to experience authentic American life, away from tourist traps.

Food in the US is as diverse as its population, although portions are usually significantly larger than in Spain. Don't limit yourself to fast food; explore regional cuisine, from New England seafood to Southern barbecue. In cities like San Francisco or Washington DC, you will find an incredible variety of international haute cuisine. In many restaurants, service is fast and efficient. If you don't finish your meal, it is common to ask for a 'doggy bag' to take the leftovers. Remember that tap water is generally safe to drink and is served free of charge in restaurants. Trying an authentic American 'diner' is a mandatory experience for any traveler.

When planning your trip, remember that distances in the US are gigantic. Do not try to cover the East Coast and the West Coast in one week. If you have secured **cheap flights from Madrid to the United States** or **cheap flights from Barcelona to the United States**, focus on one region. For example, combine New York, Boston, and Washington DC in the Northeast, or Los Angeles, San Francisco, and San Diego on the West Coast. If you are looking for **cheap Las Vegas Strip flights**, you can combine it with the Grand Canyon. Driving times between cities can be 8 to 10 hours, so it is often better to take an internal flight. Use mapping tools to calculate realistic travel times before finalizing your itinerary.
