Strategizing my Delta Companion Passes
Disclaimer: This is based on my current understanding and how I personally approach these decisions. This is a LONG post about my thought processes.
We are Delta-loyal because of where we live and our travel patterns. Kalamazoo airport only flies Delta and American (and basically only flies to Detroit Metro or O’Hare). Honolulu’s best lounge is Delta. So Delta it is.
My husband and I each have Delta-branded American Express cards that award us companion passes. Each of our cards comes with one companion pass and 4 guest passes for Delta Lounges.
AmEx Delta Reserve—currently with a $650 annual fee—is the better card for racking up Delta SkyMiles, but if I were really trying to “hack points,” being locked to Delta would be a disadvantage. If staying in the AmEx world, the AmEx Gold is better suited, as the loyalty program can convert to other airline alliances. Overall, Chase Sapphire Preferred is generally considered the strongest card for flexible airline points. Since I’m not doing that, I can’t tell you much about it. That’s an “after hubby retires” project. For now, I’m sticking with Delta and AmEx.
First, we need to understand the pass parameters. Here are the ones I find most important:
One pass per qualifying account is awarded annually at the conclusion of each membership year
You must travel with it within 365 days after it is awarded (not just book—actually fly)
It’s valid for anything north of the Panama Canal, including much of the Caribbean and Hawaii
Europe is out of range—use SkyMiles instead
You must book at least Main Cabin (no basic economy)
Some tickets may not be eligible
You still pay taxes and fees on the companion seat
The flight must be Delta branded, no partner airlines
Now that we’ve got the baseline set… where are we going with it? Well, I know I’m going to Hawaii every March for work, so that uses one for my event assistant. That leaves one for a fun trip. Let’s look at my personal parameters:
I’m an art, architecture, and history nerd
Health-wise, I’m not very heat tolerant, not very exercise tolerant, and I often use mobility aids
I have celiac, so I ideally want either a cuisine that’s naturally lower in wheat (like Mexico) or a city with strong gluten-free options
Hubby doesn’t love super crowded places
I speak remedial Spanish and would like to gain fluency
So here’s my list, based on all of that and:
At least a one-week window of 65–80°F (avoiding Feb–mid July due to work)
Cost for tourists (average meals + average 4-star hotel)
Delta-operated flights only (no partner segments—those don’t qualify for the pass)
Let’s dig into routes: My closest airport is AZO. AZO only flies to ORD or DTW. Only the DTW routes are Delta, so that dictates everything. In a perfect world, I’d have a nonstop from DTW to all sorts of glorious destinations, but using “nonstop from DTW” as a limit leaves exactly one option: MEX. Here’s how the list shakes out when I widen scope to allow an additional connection or ground transfer. We will go south first.
HIGHLANDS OF MEXICO — most costly to least
Mexico City
Temp: 68–75°F. Most stable option.
Flights: AZO → DTW → MEX (Delta nonstop)
Total average travel time: ~6–7 hours
Typical Delta fare: $600–$900
No shuttle required
Meal Out: $10–$25
4-Star Hotel: $120–$180
Rainy season with goal temps: July–September
Dry season with goal temps: November–February
Cuernavaca
Temp: 72–75°F. Warm edge of your range.
Flights: AZO → DTW → MEX → ground transfer (~1.5 hr)
Total average travel time: ~7.5–9 hours
Typical Delta fare: $600–$900
Shuttle required
Toluca
Temp: 65–72°F. Slightly cooler due to elevation.
Flights: AZO → DTW → MEX → ground transfer (~1–1.5 hr)
Total average travel time: ~7–8.5 hours
Typical Delta fare: $600–$900
Puebla
Temp: 68–74°F. Very consistent shoulder seasons.
Flights: AZO → DTW → MEX → ground transfer (~1.5–2 hr)
Total average travel time: ~7.5–9.5 hours
Typical Delta fare: $600–$900
Monterrey
Temp: 80–85°F (narrow fall window).
Flights: AZO → DTW → ATL → MTY
Total average travel time: ~7–9 hours

Cancún
Temp: 82–85°F in winter window.
Flights: AZO → DTW → CUN (Delta nonstop)
Total average travel time: ~5.5–7 hours

PUERTO RICO
San Juan
Temp: 80–85°F in winter.
Flights: AZO → DTW → ATL → SJU
Total average travel time: ~7.5–9.5 hours
Typical Delta fare: $500–$850
That’s a fair list. Interestingly, being willing to drive to or fly out of O’Hare doesn’t add any Delta options. Same for GRR, MDW, and LAN. Within this list, the sweet spot is Mexico City:
Consistent temperature across multiple months
Clean routing
No shuttle
Mid-range cost
Excellent food and museum scene
Strong transit
One of my favorite places (though hubby doesn’t care for it)
Alright, let’s actually run the numbers on SkyScanner. We will create a hypothetical trip for Sept 12–17 of this year (23 weeks from now):
My target airline - Delta: $821 (2 stops) or $1,196 (1 stop)
The cheapest fare that comes up - United: $656 (1 stop)
Depending on the Delta routing, I’m either saving about $350 total with the companion pass… or breaking even. I also know that if I leave out of O’Hare, I can get a direct flight for ~$302 per person. This seems like the obvious choice for visiting a favorite destination. Bottom line: Going from the Midwest to Mexico simply isn’t an optimal use of a companion pass.
Hawaii? Worth it. What about Alaska and Canada? Alaska is actually one of the strongest use cases for a companion pass in this system.
Delta does operate Alaska routes out of Detroit, either nonstop seasonally or with a connection through a hub like Minneapolis or Seattle. More importantly, it checks all the boxes that make the pass valuable: it’s a longer flight, fares are often higher, and it’s a route where comfort starts to matter more. That combination means the pass isn’t just saving money—it’s offsetting a flight where I might realistically consider paying for a better seat.
ALASKA — high value companion pass use
Anchorage
Temp: 55–70°F (summer peak window). Cooler shoulder seasons.
Flights: AZO → DTW → ANC (Delta seasonal nonstop) or via MSP/SEA (Delta)
Total average travel time: ~7–10 hours
Typical Delta fare: $700–$1,200
No shuttle required
Meal Out: $20–$40
4-Star Hotel: $200–$400
Peak season with goal temps: June–August
Shoulder season with goal temps: May, September
Fairbanks
Temp: 60–75°F (short summer window). Much colder outside peak.
Flights: AZO → DTW → MSP/SEA → FAI (Delta)
Total average travel time: ~9–12 hours
Typical Delta fare: $800–$1,300
No shuttle required
Meal Out: $20–$40
4-Star Hotel: $180–$350
Peak season with goal temps: June–August
Shoulder season with goal temps: May, September
Canada, on the other hand, is a very different story. Delta does fly to Canadian cities, but those routes tend to be shorter, cheaper, and often involve regional aircraft or less ideal routing. Even when the companion pass technically works, the savings are relatively small and the comfort factor doesn’t change much on a shorter flight. So while Canada is valid within the rules, it doesn’t really fit the strategy. Alaska does.
What about the West Coast? This is where things get a little more nuanced.
West Coast routes sit in an awkward middle ground. They’re not inherently expensive the way Hawaii is, but they’re not consistently cheap either—especially given my routing constraints and preference for Delta-operated flights. So the companion pass doesn’t automatically create value. It depends on how I’m using it.
From the Midwest to the West Coast, comfort starts to matter more, and I’m less willing to use a bargain airline. Delta pricing tends to be meaningfully higher than the lowest available option, but not always dramatically so. That puts these routes in a gray area. Sometimes the companion pass creates real savings. Sometimes it just brings Delta down to parity.
So instead of asking, “Is this flight expensive enough?” I’m asking: Is this a flight where I’d consider paying for a better seat?
If the answer is yes, the companion pass becomes much more powerful. Because now it’s not just offsetting a base fare—it’s offsetting the cost of a more comfortable experience. I am 50, with a bad hip. Comfort matters more every year. That’s the version of a West Coast redemption that makes sense to me.
So for the West Coast, my rule isn’t based on a specific dollar amount—just the price gap between Delta and competitors, and the comfort factor. Otherwise, I’m better off booking the cheapest reasonable flight and saving the pass for something with more built-in value.
That’s why West Coast trips aren’t automatically on my list—but they’re not off it either. They just require a bit more intention.
Now let’s expand the search beyond my temperature limitations and simply look at best bang for the buck. Let’s look at the Caribbean, where there’s no “cool weather” option for me:
HIGH VALUE REDEMPTIONS
St. Maarten
St. Thomas
San José
MID VALUE
Punta Cana
Montego Bay
Panama City
Ixtapa / Zihuatanejo
The best use of the companion pass isn’t your favorite trip. It’s the one where Delta is expensive enough—and the flight is long enough—that the pass meaningfully improves both the math and the experience.
Which is why, when I zoom out, the answer becomes pretty obvious:
Hawaii, Alaska, maybe the West Coast, and high-cost Caribbean routes. These are the trips where the pass stops being a nice perk and starts being a meaningful discount. And if I want to go somewhere like Mexico City? I should probably just book the cheapest flight and save the pass for a better opportunity. Because the goal isn’t to use the pass, it’s to use it well.
