The New United℠ Explorer Card

Limited-Time Offer: Earn 60,000 bonus miles after you spend $3,000 on purchases in the first 3 months your account is open.

Annual Fee

$150 ($0 in your first year)

The The New United℠ Explorer Card currently has a limited-time offer of 60,000 United miles after spending $3,000 in purchases on the card within three months of account opening.

Some perks of the card include:

  • Earn extra rewards when spending on United flights, bookings through United Hotels, and other travel and dining purchases
  • Get a 10,000 rewards booking discount after spending $20,000 on the card each year

If you fly United domestically and want a huge bonus worth several round-trip flights, this card is a great option.

Aeroplan® Credit Card

Rewards Rate
  • 3x points for each dollar spent at grocery stores, on dining at restaurants, and Air Canada directly
  • 1x on all other purchases
Welcome Offer

Earn up to 70,000 bonus points: Earn 60,000 bonus points after you spend $3,000 in the first 3 months your account is open, plus, earn an additional 10,000 bonus points after your annual fee renewal payment posts and is paid in full.

Chase's Aeroplan® Credit Card is currently offering 60,000 Aeroplan miles after spending $3,000 in purchases on the card within three months of account opening, plus an additional 10,000 miles at your card anniversary (after paying the annual renewal fee).

While Aeroplan miles are best for Air Canada travelers, you can use rewards to book flights on other airlines through Star Alliance, which includes United, Lufthansa, Turkish Airlines, Singapore Airlines, and others.

Perks of the card include:

  • Get immediate Aeroplan 25K Status for the rest of the year and the following calendar year
  • First checked bag free on Air Canada flights

So, if you don’t want to be tied to one specific airline while still earning airline miles, the Aeroplan® Credit Card is a compelling card to consider.

Plus, the large welcome bonus, immediate 25k status with Air Canada, and free checked bag are great perks if you regularly fly to Canada or on Canadian connections.

Hawaiian Airlines® World Elite Mastercard®

Rewards Rate

Who doesn’t dream of a tropical vacation in Hawaii? And the Hawaiian Airlines® World Elite Mastercard® can make your dream a reality with a 60,000-mile sign-up bonus after spending $2,000 within 90 days of card opening.

This card doesn’t offer the most perks, but if you’re planning a Hawaiian vacation, the large welcome bonus and Hawaiian Airlines benefits make it worth a look.

Here are some of the perks it does offer:

  • 50% off a companion fare for round-trip coach travel between Hawaii and North America
  • $100 companion pass discount each card anniversary
  • Two free checked bags
  • Hawaiian miles don’t expire as long as you hold the card

The card comes with a big welcome bonus that can potentially net you two round-trip tickets from the West Coast of the U.S. to Hawaii (if you can find discounted award availability), without a very high spending requirement.

Alaska Airlines Visa Signature® Credit Card

...
Rewards Rate
  • 3x miles on eligible Alaska Airlines purchases
  • 2x miles on eligible gas, EV charging station, cable, streaming services, and local transit purchases
  • 1x miles on all other purchases
Welcome Offer

Limited Time Online Offer: 60,000 bonus miles plus a 30% flight discount code after making $3,000 or more in purchases within the first 90 days of opening your account.

Annual Fee

$95

Alaska Airlines offers affordable flights from its main hub in Seattle, as well as all over the world.

But the only credit card that earns Alaska Airlines miles is the Alaska Airlines Visa Signature® Credit Card — which currently features a 60,000-mile welcome bonus plus a 30% flight discount code after spending $3,000 or more within the first 90 days of opening your account.

Here are some other perks:

  • 10% bonus miles when you have an eligible Bank of America® account
  • Companion pass only $99 (plus taxes) for any Alaska flight
  • Free checked bag for you and up to six additional guests on Alaska flights
  • No blackout dates or mileage earning cap

The Alaska Airlines Visa Signature® Credit Card is a no-frills rewards card that admittedly doesn’t come with a ton of benefits — but it’s the only card that earns valuable Alaska miles.

Not only can you book directly for Alaska flights, but with Alaska’s global airline partners, you can use Alaska miles to book domestic and international flights on several different airlines, including American Airlines, British Airways, Cathay Pacific, Qantas, and Qatar Airways.

Plus, the $99 companion fare ticket can be worth hundreds of dollars (or more), depending on the flight you book.

When you sign up for an airline co-branded credit card, you may be able to earn a welcome bonus. This bonus is usually a large amount of airline miles, which you earn by spending a specific amount of money within the first few months of opening the card.

For example, maybe a card offers a 70,000-mile sign-up bonus after spending $1,000 within 90 days of opening the card. Once you hit this minimum spending requirement, the bonus miles would be deposited into your airline loyalty account.

The difference between airline miles and flexible travel points

While airline cards earn miles for specific airline loyalty rewards programs, flexible travel points can be used in multiple different ways — including cashback, gift cards, travel redemptions, or transferred to other airline or hotel loyalty programs. 

For example, the Delta SkyMiles® Reserve American Express Card only earns Delta SkyMiles®. Meanwhile, The Platinum Card® from American Express earns Membership Rewards® that can be used for cashback, online purchases, or transferred to other airline and hotel partners (including Delta).

If you’re partial to one airline, it makes sense to find an airline co-branded credit card that offers a large sign-up bonus, spending bonuses, and additional perks for that specific airline. 

But if you want more options for your travel rewards, a flexible travel points card can make more sense.

Tips for Earning a Sign-Up Bonus

Before you jump on a card with a great offer, make sure you know what you’re getting into — sign-up bonuses aren’t really “free” money. 

Here’s how to make sure you earn your bonus the right way: 

  • Plan large purchases to meet minimum spending requirements. Plan larger purchases around when you sign up for the card. Also, pay for things like bills and groceries with the card to get the bonus quicker.
  • Note the spending requirement deadline. All welcome bonuses have a deadline — if you don’t spend enough by then, you’ll miss out on the bonus. Mark the deadline on the calendar and track your progress each week by adding up how much you’ve spent.
  • Pay off your statement every month. While large bonuses are nice, paying the minimum on your card and losing money to interest will negate the benefits. 
  • Avoid unnecessary spending just to earn the bonus. While a sign-up bonus can be a great way to get free flights, it’s not worth spending money on stuff you don’t need just to get a bonus. Make sure you can meet the spending requirements with things you’re planning to purchase anyway.

Maximizing the Value of Airline Sign-Up Bonuses

Getting the most from your points doesn’t mean booking the first flight you see. There are a few strategies you can use to get more out of your miles and maximize the value of each point you earn.

When to redeem miles for flights vs. upgrades

In most cases, the best value is to redeem your airline miles for flights. Search award availability to find the lowest-cost flights to make your miles stretch further. 

But for long-haul international flights, it can make sense to pay a cash fare for the main cabin and upgrade with points for a lie-flat seat in business or first class. 

You’ll need to research which airlines offer miles upgrades, and ask yourself if the miles (and fees) are worth the cost of upgrading versus saving those points for a future flight redemption.

Avoiding blackout dates and hidden fees

While using airline miles for free flights is the dream, the devil is in the details. 

Some airlines have travel award blackout dates, which prevent you from redeeming points during a specific period. This is usually during peak travel seasons (think: spring break, summer vacation, holidays). 

It’s also important to understand additional fees you might pay for booking flights. Domestic award flights usually have small fees (under $20), but international redemptions can charge hundreds of dollars for fuel taxes and other surcharges. 

Make sure to review the fees and charges on any flight you choose before booking.

Watch out for poor-value redemptions

Choosing cashback or gift cards as a way to redeem your miles is usually a very bad deal. Most cash-equivalent redemptions or “shop with points” options give you less than half the value of redeeming miles for flights. 

While sometimes you can’t avoid poor redemptions if you need to use the miles, try to avoid these low-value transactions if possible.

Bottom Line: Should You Apply for an Airline Sign-Up Bonus?

Earning airline credit card sign-up bonuses can lead to free travel, but you want to make sure you find the right bonus for your travel habits.

Only choose a co-branded credit card if it’s with an airline or alliance that you regularly fly with. If you’re not loyal to any particular airline, you may want to go for a general travel rewards credit card instead, that lets you transfer your points to a variety of partners.

Once you choose a credit card, make sure you can meet the spending requirement wisely — it’s never worth going into credit card debt for a bonus.

Yes, you can apply for multiple credit cards, but whether you qualify for the sign-up bonuses for each depends on the card issuer.

Each issuer has their own rules around the number of cards you can open, how frequently you can sign up for cards, and whether or not you qualify for multiple bonuses.

Make sure to review the terms and conditions for each card you want to sign up for before applying.

In most cases, if you return an item that helped you meet the minimum spend for a credit card welcome bonus — and it brings you below the minimum requirement — the card issuer can claw back your bonus rewards. If you’ve used the points, this could result in a negative points balance.

Some airlines have expiration dates on the airline miles you earn. You can usually extend this expiration date by spending on a co-branded credit card and earning a few more points, or making a points redemption.

While there is no legal limit to how many airline cards you can have, some card issuers restrict whether you can earn a new sign-up bonus when applying for another airline card.

It’s important to review the terms and conditions of the card issuer before applying for a second, third, or fourth airline card.
