Flights to the USA — Booking Tips, Airlines & Best Deals

The USA has the world’s largest aviation market, with hundreds of airports and dozens of airlines. For international visitors, the key decisions are which gateway airport to target and which airline alliance to use. Here is what we recommend knowing before booking.

Major International Gateway Airports

East Coast

New York JFK (JFK) is the primary transatlantic gateway and the busiest international airport on the East Coast. It handles direct flights from virtually every major world city. Located in Queens, approximately 20 km from Manhattan.

Newark Liberty (EWR) in New Jersey is the second New York-area international airport. United Airlines uses it as a major hub, and it handles extensive European, Asian, and South American traffic. Often slightly cheaper than JFK for the same routes.

Washington Dulles (IAD) is the capital region’s main international airport, about 42 km west of central Washington DC. It serves as a United Airlines hub with strong transatlantic and Middle Eastern connections.

Boston Logan (BOS) is well-connected to Europe, particularly Ireland and the UK. JetBlue uses it as a base, and flight times to London are among the shortest transatlantic crossings (approximately 6 hours 30 minutes).

Miami (MIA) is the primary gateway for flights from Central America, South America, and the Caribbean. American Airlines hub.

West Coast

Los Angeles (LAX) is the busiest West Coast international airport and the primary gateway for transpacific flights from Asia and Oceania. Flight time from London is approximately 10 hours 30 minutes.

San Francisco (SFO) handles significant transpacific and European traffic. United Airlines hub. Popular with tech industry travellers and well-connected to East Asia.

Central

Chicago O’Hare (ORD) is a major hub for both American Airlines and United Airlines, and the most connected airport in the central US for international flights. It receives direct flights from Europe, Asia, and the Middle East.

Dallas/Fort Worth (DFW) is the largest American Airlines hub and handles international traffic from Europe, Asia, and Latin America.

Atlanta Hartsfield-Jackson (ATL) is the world’s busiest airport by passenger numbers. Delta’s primary hub, with direct flights to Europe, Asia, Africa, and South America.

Other Notable Airports

Seattle (SEA) is a growing transpacific gateway, particularly for flights to East Asia. Denver (DEN) has expanding international service. Houston George Bush (IAH) serves as a United hub with strong Latin American connections. Philadelphia (PHL) is an American Airlines hub with European routes. Detroit (DTW) is a Delta hub with useful transatlantic connections.

Airlines Serving the USA

From the UK, British Airways, Virgin Atlantic, American Airlines, United Airlines, and Delta operate extensive direct services from London Heathrow. Norwegian and JetBlue offer budget-conscious alternatives on select routes. Aer Lingus via Dublin provides competitive transatlantic fares with US preclearance in Ireland. Direct flights also operate from Manchester, Edinburgh, and Birmingham to various US cities.

From Europe, virtually every European flag carrier flies to the US. Lufthansa, Air France, KLM, Iberia, SAS, Swiss, Austrian, and TAP Portugal all operate direct transatlantic routes. Budget long-haul options include Norse Atlantic Airways from London Gatwick and French Bee from Paris.

From Asia, direct flights operate from Tokyo, Seoul, Beijing, Shanghai, Hong Kong, Singapore, Taipei, Delhi, Mumbai, and other major cities on carriers including ANA, JAL, Korean Air, Cathay Pacific, Singapore Airlines, EVA Air, Air India, and the US carriers.

From Australia and New Zealand, Qantas, United, and American Airlines operate ultra-long-haul routes to LAX, SFO, and Dallas. Flight time from Sydney to LAX is approximately 13-14 hours.

From the Middle East, Emirates, Etihad, Qatar Airways, and Saudia connect via their Gulf hubs to multiple US cities with single-stop itineraries.

Best Time to Book for Deals

US flight pricing varies significantly by route, but general patterns hold. Peak periods are mid-June through August (summer holidays), Thanksgiving week (late November), and late December through early January (Christmas/New Year).

The cheapest fares typically appear for January through early March and late October through mid-November departures. April to May and September offer a good balance of reasonable fares and pleasant weather in most of the country.

For the best prices, we recommend booking 2 to 4 months ahead for transatlantic flights and 3 to 6 months ahead for transpacific routes. Tuesday and Wednesday departures are consistently cheaper than weekend flights on most transatlantic routes.

Return flights from London to New York start from approximately £300-400 in off-season, rising to £600-900 in peak summer as of 2026. Budget carriers like Norse Atlantic can bring off-peak returns under £250. From London to Los Angeles, expect approximately £400-550 in shoulder season, rising to £800+ in summer as of 2026.

Domestic Flights Within the USA

The US domestic aviation market is enormous. For distances over approximately 500 km, flying is almost always faster than driving, and the country lacks the high-speed rail network that makes train travel competitive in Europe or East Asia.

Key domestic routes for visitors:

• New York to Los Angeles: approximately 5 hours 30 minutes
• New York to Miami: approximately 3 hours
• Los Angeles to San Francisco: approximately 1 hour 20 minutes
• Chicago to New York: approximately 2 hours 30 minutes
• New York to New Orleans: approximately 3 hours 30 minutes

Southwest Airlines, JetBlue, Spirit, and Frontier are the main budget domestic carriers. American, Delta, and United handle the bulk of domestic traffic with extensive route networks.

Domestic one-way fares start from approximately $50-80 on budget carriers if booked ahead as of 2026. Booking domestic flights separately from your international ticket (rather than as an add-on connection) often saves money, though it means you bear the risk if your international flight is delayed.

Budget Tips

Fly into secondary airports. Newark instead of JFK, Oakland (OAK) instead of SFO, Fort Lauderdale (FLL) instead of Miami, and Burbank (BUR) or Long Beach (LGB) instead of LAX can all save money. Ground transport between these alternatives and the main city is usually straightforward.

Consider open-jaw itineraries. Flying into New York and out of Los Angeles (or Miami in, Chicago out) avoids backtracking and often costs no more than a standard return, while covering more of the country.

Use budget long-haul carriers. Norse Atlantic Airways, French Bee, and JetBlue’s transatlantic service offer lower base fares than legacy carriers, though amenities and luggage allowances differ.

Book domestic legs separately. If your US itinerary includes internal flights, comparing prices as separate bookings versus add-on connections can reveal significant savings. Southwest and JetBlue frequently undercut the legacy carriers on popular tourist routes.

Be flexible on gateway city. If your US trip starts with a road trip or includes multiple cities, compare fares to all nearby airports. The price difference between flying into Boston versus New York, or San Francisco versus Los Angeles, can be substantial.

Watch for airline sales. US carriers run frequent promotional sales, particularly in January (for spring/summer travel) and September (for autumn/winter travel). Signing up for fare alerts on comparison tools catches these automatically.

Entry Requirements for International Visitors

Most visitors from Visa Waiver Programme countries (including the UK, most EU nations, Australia, Japan, and South Korea) need an approved ESTA (Electronic System for Travel Authorization) before boarding. Apply online at least 72 hours before departure — it costs $21 and is valid for 2 years as of 2026.

Visitors from non-VWP countries need a US visa, which requires an embassy or consulate appointment. Processing times vary; apply well ahead of your travel date.

All international arrivals go through US Customs and Border Protection at the first US airport of entry, even if connecting to a domestic flight. Allow at least 2-3 hours for connections at busy airports like JFK, LAX, and Miami — immigration queues can be lengthy.

Getting from the Airport to the City

JFK to Manhattan: The AirTrain to Jamaica Station plus the LIRR to Penn Station takes approximately 50 minutes total for approximately $12 as of 2026. The AirTrain to the A train subway is cheaper (approximately $10 total) but slower. Taxis have a flat fare of $70 plus tolls and tip.

Newark to Manhattan: The AirTrain plus NJ Transit train to Penn Station takes approximately 40 minutes for approximately $16 as of 2026. Considerably cheaper than a taxi ($80-100+).

LAX to downtown LA: The LAX/Metro connector to the Metro C (Green) line is the cheapest option. Ride-hailing (Uber/Lyft) costs approximately $30-50 depending on traffic and time of day as of 2026.

Chicago O’Hare to downtown: The CTA Blue Line train takes approximately 45 minutes to the Loop for $5 as of 2026 — one of the best airport rail connections in the country.
