Frequently asked questions

Are there direct flights from Dulles Intl. Airport to Tribhuvan Intl. Airport?
Qatar Airways, Emirates and Turkish Airlines will get you to Kathmandu from Sterling with only one stopover. Unfortunately, there are no direct flights between IAD and KTM as yet.
What airlines fly from Dulles Intl. Airport to Tribhuvan Intl. Airport (KTM)?
You'll need to make at least one stopover if you're on your way from IAD to Tribhuvan Intl. Airport (KTM), as no airlines operate direct flights between these destinations. Make the most of your layover time by freshening up, giving your legs a stretch and checking out what the stores have on offer.
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.
