For example, a direct flight from New York City (JFK) to London (LHR) takes approximately 6 hours and 30 minutes. A flight from Los Angeles (LAX) to Paris (CDG) may take around 11 hours, while a flight from Sao Paulo (GRU) to Lisbon (LIS) might last about 9 hours.
It's important to note that these are just approximate flight times and can vary due to factors such as weather conditions, air traffic, and the specific route taken by the airline.
