Companion Certificates: The Most Underused Airline Credit Card Benefit

A companion certificate is one of the most valuable perks an airline credit card can offer — and one of the most misunderstood. Used correctly, it can get two people on a round-trip flight for roughly the price of one. Used wrong (or not at all), it expires unused while you pay full price for seats.

This guide covers every major companion certificate on the market, the restrictions you need to know, and exactly how to maximize the benefit.

What Is a Companion Certificate?

A companion certificate (also called a companion fare, companion ticket, or companion pass) lets you bring a second passenger on your flight for a reduced cost — usually just taxes and fees, or a fixed low fare — when you buy one full-price ticket.

The key mechanics:

• You must purchase one eligible base fare (varies by card/airline)
• The companion pays only fees/taxes or a discounted fare, typically $22–$100
• Certificates are issued annually, usually after your card anniversary
• Blackout dates and seat restrictions often apply

The dollar value can be enormous. A round-trip ticket from New York to Honolulu runs $500–900 in economy. Bring a companion for $22 in taxes, and you've generated $480–880 in value from a single certificate.

Every Major Companion Certificate, Compared

Alaska Airlines Visa Signature (Bank of America)

Certificate value: One companion flies round-trip for $0 + taxes/fees (~$22–$130 depending on route)

How you earn it: Issued each year after your card anniversary. You also earn a second certificate if you spend $6,000+ in a calendar year.

Eligibility: Must purchase a full-price "Companion Fare" eligible ticket on Alaska Airlines

Restrictions:

• Companion must travel on the same itinerary as the primary cardholder
• No first class (economy and Premium Class only, depending on offer)
• Award tickets and discounted fares don't qualify as the base ticket

Best use case: Alaska routes to Hawaii, Mexico, and the Pacific Northwest, where round-trip fares regularly hit $400–700. Companion saves the full cost of a second ticket minus ~$22 in fees.

Annual fee: $75

Verdict: One of the most valuable companion certificates available. The low fees and generous route network make this a consistent top pick for frequent Alaska flyers.

Southwest Rapid Rewards Priority / Performance Business Cards

How this is different: Southwest doesn't technically issue a "companion certificate" from its consumer cards. Instead, the famous Companion Pass requires earning 135,000 qualifying points in a calendar year — after which your designated companion flies free on every flight, for the rest of that year plus the next full year.

This is a different beast from the annual certificate model. The setup requires deliberate point earning (welcome bonuses, spending), but the payoff is enormous: unlimited free companion travel for up to 25 months.

Optimal earning strategy:

• Apply for two Southwest cards (personal + business) in the same calendar year
• Welcome bonuses alone often push you close to or past 135,000 points
• Current typical offer: 75,000 points per card

Annual fee: $149–$199 (Priority), $199 (Performance Business)

United Explorer Card (Chase)

No traditional companion certificate — but the card offers 2 United Club one-time passes annually and 25% back on in-flight purchases. For companion-style benefits on United, look at the United Quest Card, which offers $125 in statement credits on United purchases annually.

For true companion fares on United, the best route is through United MileagePlus awards (Saver awards can sometimes be booked as two one-ways at the same price as one), rather than a card-specific certificate.

How to Maximize Your Companion Certificate

Book the Right Fare Class

The companion certificate only applies when you purchase a full-price eligible base fare — usually the standard economy or "Main Cabin" fare, not the cheapest Basic Economy option. Before booking, confirm:

1. The fare class qualifies (check the card's terms — often excludes "saver" or "light" fares)
2. You're booking directly through the airline's site or app, not a third-party OTA
3. You apply the certificate at checkout, not after the fact

Time Your Booking Around Peak Routes

Companion certificates are worth more when the base fare is high. Book companion certificates on:

• Holiday travel windows (Thanksgiving, Christmas, spring break)
• Peak summer routes (beaches, Hawaii, Europe if eligible)
• Long-haul domestic routes (cross-country)

Avoid wasting them on $150 round-trips where the math barely justifies the effort.

Don't Forget the Expiration Date

Most certificates expire 12 months after issuance (with some variation). Check your card's anniversary date and track when the certificate was issued. Set a calendar reminder 60 days before expiration — that's enough lead time to book a trip worth taking.

Pair with Points, Not Just Cash

If you're using an airline credit card anyway, you're likely accumulating miles. Stack the companion certificate with a miles redemption: buy one ticket with cash (triggering the companion certificate), and use miles to offset or cover a future segment. Or use the companion on a premium route and bank the miles from that purchase toward the next trip.

Plan the Trip Before You Worry About the Certificate

One mistake travelers make: they hold the certificate "for the right trip" and it expires unused. The better approach is to let the certificate be the trigger for planning a trip — not the other way around.

That's where Faroway helps. Once you know your companion certificate is active, put in your departure city, the airline you're holding the certificate for, and what kind of trip you're looking for. Faroway's AI builds a full itinerary — days, activities, logistics — around the destination, so you're not just booking a flight, you're booking a trip worth taking.

Whether you're using Alaska's nearly-free Hawaii companion or Delta's domestic certificate, the hardest part is often deciding where to go and what to do once you get there. Let the AI handle that so you can focus on actually going.

The Bottom Line

Companion certificates are among the few credit card benefits that can generate $500+ in value from a single use. The Alaska Airlines Visa is the standout for most travelers — low annual fee, minimal restrictions, and genuinely cheap companion fees. Delta Platinum Amex is worth it if you're a frequent Delta flyer with international aspirations. And if you're willing to put in the work, the Southwest Companion Pass is the most powerful unlimited companion benefit in the industry.

The key is knowing you have the certificate, understanding the restrictions before you need them, and booking proactively — not scrambling to use it two weeks before it expires.
