Find and Book Cheap Flights to the United States from South Korea

Winter (December to February) is one of the cheapest times for flight tickets. It is great for planning trips to warm southern regions or ski resorts. Colder northern areas are quiet with fewer tourists.

Spring (March to May) brings pleasant weather across the United States, and flight prices begin to rise. It's a great time for outdoor sightseeing and festivals, making it ideal for US travel.

Summer (June to August) is the peak travel season in the US, and round-trip flight prices are the highest. It's the best time to visit national parks or enjoy beach holidays. Flights must be booked well in advance.

In autumn (September to November), peak season ends and flight prices start to drop again. November is typically when US airfares become cheaper. The fall foliage in the Eastern region is spectacular.

South Korean nationals can enter the United States for tourism or short business purposes for up to 90 days through the Visa Waiver Program (ESTA). ESTA must be applied for online at least 72 hours before departure and is valid for two years upon approval. If ESTA approval is denied or if you plan to stay longer than 90 days, you must obtain a separate visa. Ensure your passport is valid for at least six months beyond your intended stay. It is crucial to enter accurate information when applying for ESTA.

Since the United States is vast, domestic flights (US domestic flight prices) are the fastest way to travel between cities. Major cities like New York and Chicago have good subway and bus systems, but a rental car is essential in areas like Los Angeles and other regions. When renting a car, you will need your South Korean driver's license and an International Driving Permit; be sure to thoroughly check insurance coverage. In large cities, traffic congestion is severe and parking can be expensive, so using public transport or ride-sharing services is often recommended. Trains or intercity buses can also be considered for long-distance travel.

Accommodation in the US varies, including hotels, motels, and Airbnbs. Hotels in major city centers are expensive but offer good accessibility, while motels on the outskirts are relatively cheaper and usually provide ample parking. Accommodation prices increase significantly during peak season (compare US peak season flight prices), so booking early is crucial. When booking, check the final price to ensure it includes taxes and any Resort Fees. For safety, consider the location's security and access to public transportation when choosing where to stay.

Security conditions in the United States vary greatly by region. In large cities, even in tourist areas, avoid walking alone late at night and be wary of approaches from strangers. Pickpocketing or robbery can occur, especially in places like New York or LA. Use credit cards instead of carrying large amounts of cash, and always keep your bag close to you in public places. In an emergency, dialing 911 will connect you to police, fire, or ambulance services. Purchasing travel insurance is highly recommended and essential for any trip.

Tipping culture is highly developed in the United States. It is customary to leave a tip in various places, including restaurants, taxis, and for hotel services. In restaurants, a tip of 15–20% of the pre-tax bill is standard. Tipping is a main source of income for service providers, so it is local custom to tip if you receive service. Additionally, Americans tend to value personal privacy, so it is best to avoid asking personal questions to people you have just met. Be mindful of maintaining order and avoiding causing disturbances in public spaces.

As the US is home to diverse ethnic groups, you can find cuisine from all over the world. Besides American staples like hamburgers, steaks, and pizza, Mexican, Italian, and Asian foods are common. Portions in restaurants are often very large, so you may want to confirm the size when ordering or request a takeaway box (To-go). In non-fast-food restaurants, you sit down, order, and ask for the check after eating. If you don't specifically ask, you will usually be served ice water (tap water). Be sure to experience the diverse regional specialties.

The climate difference across regions in the US is significant, so check the weather of your destination city and pack appropriate clothing. Since many areas experience large temperature swings between day and night, it is good to pack light outerwear. The US uses 110V, so a voltage converter or adapter is essential for using electronic devices brought from South Korea. Also pack essential medicines, sunscreen, and comfortable shoes. Crucially, check the baggage allowance rules when booking your flight ticket to avoid incurring extra fees at the airport.

Beyond major tourist sites, try visiting small neighborhood markets or parks frequented by locals. In New York, explore small cafes in Brooklyn, and in LA, wander through the backstreets of Venice Beach. Dining at small restaurants recommended by locals and using public transport to immerse yourself in the city's daily life are great experiences. By respecting the local culture and traveling at a relaxed pace, you can discover a deeper, more authentic side of the United States.
