How to Stack Miles, Credits, & Passes Step-by-Step

Use the following workflow to minimize out-of-pocket costs while maximizing perks.

01

Review Each Program’s Fine Print

Before planning your trip, check the terms for your airline, credit card, and companion pass.

For example, some airlines won’t let you apply travel credits to mile bookings, and companion fares may only work on paid tickets.

02

Identify Eligible Flights and Fares

Run searches for your desired route to see which options allow all benefits.

Look for paid fares that support both travel credits and companion passes, and note if you might be able to use miles for an additional ticket.

03

Apply Credits and Passes in the Right Order

Sequence usage to avoid losing value or getting blocked.

Typically, use travel credits first when booking paid fares, add the companion pass to the same reservation, then use miles for additional travelers.

04

Finalize and Monitor Reservations

Double-check confirmation emails for correct application of each benefit.

Set a calendar reminder for any unused credits or passes before they expire after booking.

Critical Layers for Combining Benefits

001

Rules Awareness

Every stackable perk has restrictions. Memorize which can be combined in advance.

002

Timing

Some credits or passes must be applied at booking—wait and the window may close.

003

Expiration Tracking

Monitor all perks’ expiry dates month to month for last-minute usage opportunities.

Real-World Scenarios

Southwest Companion Pass + Travel Credit

Situation: You have a $75 Southwest credit and a Companion Pass.

Move: Book a paid fare for yourself using the credit, then add the companion. Miles can be used for a third ticket if needed.

Delta Companion Ticket + Miles

Situation: Annual Delta companion certificate and SkyMiles available.

Move: Book two paid fares—one with the certificate, pay out-of-pocket or with eligible credit; use miles for a third ticket if you can't use credits on awards.

Expiry Juggle

Situation: Chase Sapphire and Amex Platinum travel credits both expiring soon.

Move: Prioritize applying credits to paid fares that also allow companion pass usage; book award tickets with miles only after credits are used.

FAQ

Generally, companion passes are only valid on paid (cash) tickets, not on award bookings using miles.

How do I maximize expiring travel credits?

Prioritize using expiring credits for paid fares, especially those allowing companion pass stacking, before considering booking with miles.
