Newark Liberty International (EWR) serves as a major international and transatlantic gateway for the New York metro area and often handles a mix of full-service global carriers alongside some low-cost and regional operators. Located in Newark, New Jersey, it sits roughly 15–20 miles from Manhattan; travel times to Midtown can range from about 25–45 minutes by direct NJ Transit or Amtrak trains plus short transfers, or 30–60+ minutes by road depending on traffic, with fares typically moderate for public transit and higher for taxis or ride-shares. Pros: extensive international connections and strong rail links; cons: can be busy and subject to New York-area traffic and occasional delays. John F. Kennedy International (JFK) is New York’s principal long-haul and international hub, commonly used by large network carriers and many international airlines, while also serving some low-cost carriers. It lies about 15–18 miles southeast of Manhattan; the AirTrain connects to NYC Subway and Long Island Rail Road with total journeys commonly around 35–60 minutes, or 45–90+ minutes by car depending on traffic, with public-transport fares usually lower than taxi or rideshare options. Pros: broad nonstop long-haul service and modern terminal options; cons: spread-out terminals, busy peak periods, and variable road congestion. LaGuardia Airport (LGA) typically functions as a primarily domestic and short-haul airport, favored by many U.S. network carriers and several low-cost airlines for regional and domestic routes. Located in Queens about 8–10 miles from Midtown Manhattan, travel times are often 15–35 minutes by car without heavy traffic and 30–60+ minutes when congested; limited public-transit options (bus and subway connections) can make journeys longer though usually more affordable. Pros: close proximity to Manhattan and frequent short-haul flights; cons: primarily domestic routing, fewer long-haul options, and potential road congestion during peak times. Stewart International Airport (SWF) is a smaller, more budget-oriented option north of the city that can be used for low-cost and seasonal routes, often appealing to leisure travelers seeking lower fares. It sits roughly 60–65 miles from Midtown Manhattan; typical travel times are about 70–100+ minutes by car and longer by public transit combinations, with shuttle or coach services available at modest fares. Pros: lower crowding and sometimes cheaper tickets; cons: considerably farther from the city center and fewer scheduled flights and amenities.

McGhee Tyson Airport (TYS) serves Knoxville as the region’s primary commercial gateway, typically handling a mix of legacy and low-cost carriers on domestic routes; it can be perceived as moderately priced compared with larger hubs. Located about 12 miles south of downtown Knoxville, travel times are generally 20–30 minutes by taxi or rideshare and roughly 30–45 minutes by local bus, with fares usually ranging from modest transit fares to higher ride-share costs. The airport is compact and easy to navigate, which can make connections convenient, though flight options may be fewer than at major international hubs. Its proximity to the city and straightforward layout are advantages, while limited international connections and fewer late-night departures can be drawbacks for some itineraries.
