Finding affordable airfare often comes down to timing—when you book, and when you fly. If you're planning to travel with United Airlines, knowing the best day to book can make a real difference in how much you pay. While pricing is never completely predictable, certain trends can help you make smarter decisions. This guide breaks down those trends and offers tips to help you find the best deals, including when to book, which days to fly, and how to stay flexible.

Why Flight Prices Change

Airlines use dynamic pricing, meaning ticket prices change based on demand, availability, season, and competition. United Airlines, like most major carriers, adjusts prices frequently—sometimes multiple times a day. Because of this, there’s no single rule that applies in every situation. However, patterns do exist, and those can be used to your advantage.

Best Days to Book United Flights

1. Tuesday and Wednesday

Data from travel industry sources consistently shows that Tuesdays and Wednesdays tend to offer some of the lowest airfares. Airlines often release sales early in the week—usually late Monday or early Tuesday. By midweek, competing airlines, including United, adjust their pricing to match or beat each other. If you're looking for a good price, it’s worth checking fares on Tuesday afternoon or early Wednesday.

Booking midweek also means you’re less likely to be competing with weekend travelers, which keeps demand lower and fares more stable. If you want help comparing options or booking over the phone, customer support is available at +1-855-660-4192.

2. Saturday

Surprisingly, Saturday can also be a smart day to book. With fewer business travelers browsing flights and lower overall search volume, some deals tend to surface. It’s a good idea to check fares over the weekend, especially if you’re planning a trip a few months out.

Cheapest Days to Fly

Booking on the right day is important—but flying on the right day can be just as crucial. Based on pricing trends:

• Tuesdays, Wednesdays, and Saturdays are often the least expensive days to fly.

• Fridays and Sundays are typically more expensive due to higher demand from weekend travelers and business flyers returning home.

If you can be flexible with your travel schedule, shifting your departure or return to one of the less popular days can lead to significant savings.

Is There a Best Time of Day to Book?

Some travel sites suggest that early morning hours—especially between 6:00 AM and noon—are ideal for finding lower fares. This is often when airlines refresh their inventory, update prices, or release unsold seats.

It’s not a strict rule, but checking prices in the morning could give you an edge. If you're unsure whether the price you're seeing is a good one, or if you'd like assistance reviewing your options, feel free to contact +1-855-660-4192.

Helpful Tools and Tips

To stay informed and catch deals when they appear, consider using tools like:

• Google Flights – for viewing fare calendars and tracking prices.

• Hopper – which predicts price changes and recommends when to book.

• United’s official site – sometimes features promotions or offers for MileagePlus members.

Also, setting up price alerts for your route allows you to get notified when fares drop. If you prefer talking to someone directly, a representative at +1-855-660-4192 can help you track fares and find competitive options.

Additional Strategies for Saving

Besides knowing the best days, here are a few more ways to book smarter:

• Book in advance: For domestic United flights, booking 1–3 months ahead is often ideal. For international routes, 2–6 months tends to be better.

• Stay flexible: Use flexible date search features to compare prices across different days.

• Avoid peak travel periods: Fares typically increase during major holidays, spring break, and summer.

• Use loyalty points: United’s MileagePlus program lets you earn and redeem miles, potentially saving you money or unlocking upgrades.

• Check alternate airports: If you’re flying into or out of a large metro area, look at nearby airports for better fares or flight times.

If you’d like to discuss flight options, alternate routes, or booking with miles, you can speak with someone directly by calling +1-855-660-4192.

Common Misconceptions

A few booking myths are worth clearing up:

• Last-minute isn’t always cheaper: While it might work for low-cost carriers, United generally raises prices closer to the travel date.

• Clearing cookies doesn’t significantly affect fares: Most pricing is based on demand, not your browsing history.

• Weekends aren’t always cheaper to book: In fact, midweek is more reliable for lower prices.

Knowing the facts can help you avoid overpaying and make confident decisions when booking.

Final Thoughts

There’s no single guaranteed day when United Airlines offers the cheapest fares, but booking on Tuesdays or Wednesdays—especially in the morning—often gives you the best chance. If you can also fly on off-peak days like Tuesday, Wednesday, or Saturday, you’re more likely to find competitive prices.

Keep an eye on fare trends, stay flexible when you can, and use available tools to compare your options. If you’d rather book with the help of a travel expert or just want to double-check that you’re getting the best price, you can always call +1-855-660-4192 for assistance.
