Frequently asked questions

Are there direct flights from Denver Airport to San Diego Airport?
Sometimes, it's the journey that counts; other times, the magic is in the destination. But if you just want to get to where you're going fast, multiple airlines advertise direct flights from Denver Airport to San Diego Airport, including Southwest Airlines and United Airlines.
What airlines fly from Denver Airport to San Diego Airport?
You can take your pick from a few airlines with direct flights between Denver and San Diego County. Southwest Airlines (WN) is one of the most reliable. This carrier operates around 178 flights each month. If that's not enough for you, have a look at the deals on offer from United Airlines (UA). This carrier operates 152 flights every month. Between the two, you're sure to find the flight to suit your travel plans.
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.
