Are there direct flights from McGhee Tyson Airport (TYS) to Buffalo Niagara Intl. Airport (BUF)?
If you'd rather get as quickly as possible from McGhee Tyson Airport (TYS) to Buffalo Niagara Intl. Airport (BUF), look into American Airlines, Delta and United Airlines. No airlines provide nonstop flights on this route, so you'll need to make at least one stopover.
What airlines fly from Knoxville Airport to BUF?
Unfortunately, there are no airlines offering direct flights between Knoxville Airport and Buffalo Niagara Intl. Airport (BUF). For the sake of saving time, plan well in advance to find the best price and route.
What is the best day to buy a plane ticket?
Airfares offered on Friday tend to be the cheapest, according to flight demand on Travelocity.ca in 2021. Purchasing your airfares on a Thursday or Saturday can also provide better value, however our advice if you're looking to save money is to avoid booking on a Wednesday or Sunday. Our data shows that those two days have the highest ticket values on average, so keep this in mind if you're browsing flight deals.
What are the cheapest days to fly?
Frequent travellers may already know this, but earlier in the week is often the cheapest time to fly. Flights departing on a Monday are the cheapest of the week. Since flights towards the middle of the week tend to be more popular, this causes the prices to rise. This is why, on average, airfares booked on Travelocity.ca in 2021 were most expensive for Wednesday departures.
How far in advance can you book a flight?
Here's the deal: It is typically possible to start comparing international airfares on Travelocity.ca up to 12 months in advance. However, it does depend on the carrier as not all airlines release their prices that far out. According to our 2021 flight demand trends, last minute planners can still bag a bargain with some of the cheapest fares appearing 2-4 weeks prior to their travel dates.*According to flight demand on Travelocity.ca from January to December 2021. Savings are subject to change and may vary depending on selections made.
