What are the cheapest flights and most expensive flights?

How have flight prices changed in recent years?
Since 2021, the average price of a roundtrip ticket has increased 29%, meaning people are paying $86 more than they were just a few years ago.1
What’s behind these airfare increases? Greater demand, higher fuel prices and airline capacity issues are the main reasons for the increase in flight costs. However, price hikes have hit some airports harder than others.
Minneapolis-St. Paul Regional Airport has experienced the biggest increase in average airfare by origin city at 48%. In all, flight prices have increased at 97 of the nation’s 100 busiest airports.
What is the busiest airport in the United States?
Atlanta’s Hartsfield-Jackson International Airport is the busiest airport in the United States, with 61,226,507 passenger seats available in 2023.5 The table below showcases the top 10 busiest airports in the U.S. last year.
What is the busiest airport in the world?
Atlanta’s Hartsfield-Jackson International Airport isn’t only the busiest airport in the United States, it’s also the busiest airport in the world. Dubai International and Tokyo International round out the top three, but in all, five of the 10 busiest airports in the world are located in the U.S.5
What are the busiest air travel days of the year?
Sunday after Thanksgiving is the busiest travel day of the year at U.S. airports. Last year, 2,908,785 people flew nationwide on that day.6 Traveling around Christmas can also be chaotic, especially on Dec. 22.
Of the 15 busiest days of the year for air travel at U.S. airports, most occur during the summer months of June and July, though October also has its fair share of busy air travel days.
The slowest plane travel day is Jan. 31, with 1,534,786 people traveling through America’s airports. On average 2,352,187 people travel by plane each day in the U.S.
What are the busiest months for air travel?
Despite dates in November and June being the top two busiest days for air travel last year, the busiest month for air travel overall was July. In July 2023, 79,847,051 people traveled by plane in the U.S.
June and August were similarly busy, with roughly 77 million and 75 million air travelers respectively. February is the slowest travel month of the year, with 58.3 million passengers in the United States, though it also has fewer days than other months.
The table below shows the total passenger volume at U.S. airports each month in 2023.
What is the cheapest day of the week to fly?
Tuesday and Wednesday are the cheapest days to fly domestically, according to data from Hopper.7 Saturday and Sunday are the most expensive days to fly within the U.S.
Below is the average airfare for each day of the week for domestic flights.
When is the best time to book a flight?
The best time to book a flight is 25 to 38 days before departure if you are traveling domestically, according to Expedia.8 The best time to book a flight if you are traveling internationally is about two months before departure, though you are taking a gamble that flights won’t sell out by then.
Booking a domestic flight a month before departure is 10% cheaper than booking at the last minute, on average. Booking for international flights peaks early — you’ll generally need to buy your tickets six months before departure to save that 10% on airfare.
Which airline has the most canceled or delayed flights?
Frontier Airlines had the most delayed flights in 2023, with 33% of flights delayed. Delta Airlines had the fewest delayed flights; only 16% of Delta flights were delayed last year.1
JetBlue had the highest number of canceled flights in 2023, with more than 2.6% of flights getting canceled. Alaska Airlines had the fewest canceled flights in 2023. Less than 1% of the airline’s flights were canceled in 2023.1
Buying travel insurance can help protect you financially if your flight is delayed or canceled. Trip delay is one of the key things covered by travel insurance. Given the major issues airlines have with daily flight cancellations and delays, getting an affordable travel insurance policy is a wise idea.
Below is a list of each major airline’s percentage of on-time, delayed, canceled and diverted flights. In all, 77% of airline flights were on time, 21% were delayed, 1.45% were canceled and 0.25% were diverted in 2023.1
How much is travel insurance?
Given the volatility of the airline industry, it’s a good idea to purchase comprehensive travel insurance when booking a flight. On average, travel insurance costs between 5% and 6% of your nonrefundable trip expenses.
That means insuring a $10,000 trip (all nonrefundable) might cost $500 to $600. Insuring a much less expensive trip (say $1,000) would thus be more affordable ($50 to $60).
