Flight prices are always moving. One day they’re low, the next day they’ve doubled. But if you understand how the system works, you can avoid paying more than necessary. This guide is here to help you do just that.
And if it ever feels like too much? Just call Airline Help at 800-594(4991) (OTA) — we’ll search, compare, and book the best flight for you.
What’s the Best Day to Book United Airlines Flights?
➡️ Short answer: Tuesday
Tuesday is often when airlines release new fares and update their systems. By Tuesday afternoon, competitors match those prices. This creates a “fare war,” which is good news for you.
That means Tuesday afternoon into Wednesday morning is the prime time to buy your ticket. You’ll see price drops on routes across the board, not just with United.
A Quick Tip: Try searching for flights after 3 PM on Tuesdays for the best shot at getting a lower fare.
Planning a united airlines flight booking on a tight budget? This trick can easily cut your cost.
What Time of Day Should You Book?
Flight prices don’t just shift by day—they shift by the hour.
Best times to search:
- Early morning: 6 AM – 9 AM
- Late evening: 8 PM – 11 PM
This is when airlines often refresh their systems. Cancellations from other bookings get released, and new fare buckets open up.
⛔ Avoid mid-day if you can. That’s when search traffic is highest, and prices may climb temporarily.
This tip also helps if you’re trying to rebook after a united airlines missed flight and want to avoid peak pricing.
Use United’s Low Fare Calendar to Your Advantage
United Airlines has a tool that many travelers miss: the Low Fare Calendar.
This tool shows you an entire month’s worth of flight prices at once, so you can compare day by day. If your dates are flexible, it’s a goldmine.
Here’s how to use it:
- Head to united.com
- Click “Book”
- Choose “Flexible Dates”
- Select your departure and return cities
- Pick a month and hit Search
You’ll see the lowest fare for each day side-by-side—perfect if you’re open to flying on a Tuesday or Wednesday instead of a weekend.

How Far in Advance Should You Book?
Booking early often saves money—but how early?
Based on trends:
| Trip Type | ⏳ Book This Early |
| Domestic Flights | 6 to 10 weeks before travel |
| International | 2.5 to 5 months in advance |
Don’t wait until the last minute hoping for a miracle deal—especially if you want to avoid a United Airlines missed flight situation.
⚠️ What About Last-Minute Deals?
Last-minute fares do happen—but they’re risky. If you’re flexible, you might score a deal. But if your dates or destination are fixed, it’s better to book early and lock it in.
Tip: Book early for peace of mind. Deals can come and go in hours.
What Are the Cheapest Days to Fly United?
Booking on the right day is one thing. Flying on the right day matters, too.
✅ Best days to fly:
- Tuesday
- Wednesday
- Saturday (early morning only)
These are high-demand travel days, and prices tend to spike. If you must travel on these days, confirm details early to prevent a United Airlines missed flight due to full capacity or delays.
⛔ Avoid flying on:
- Fridays
- Sundays
- Holiday weekends
These are peak travel days, with higher demand and higher fares.
Fly During Off-Peak Hours
You can also save by choosing less popular flight times.
Try to fly:
- Before 8 AM
- After 9 PM
Off-peak flights are cheaper, quieter, and more likely to stick to schedule—avoiding sudden changes or stress that may result in a United Airlines missed flight.
5 More Ways to Save on United Flights

2️⃣ Compare Nearby Airports
Flying out of or into alternate airports can cut your price. For example, try Newark instead of JFK or BWI instead of DCA.
