Complimentary upgrades clear by tier window on eligible fares; certificates confirm where U is open from 72 hours out, in status order. Reviewed September 8, 2026. Alaska upgrades come in two forms through Atmos Rewards: complimentary status upgrades that every elite tier receives automatically on eligible fares, and shareable upgrade certificates earned at elite milestones. Both clear against the same U-class first-class inventory, so on any given flight the real question is whether U class is open. That is what to check first. ## Complimentary status upgrades All Atmos Rewards elite members are automatically placed on the upgrade waitlist when booking eligible economy fares. No action required — upgrades clear based on availability and tier priority. | Atmos Tier | Window | Eligible flights | | :--- | :--- | :--- | | Titanium | 120 hours | AS + HA North America, plus long-haul Business outside North America | | Platinum | 120 hours | AS + HA North American routes | | Gold | 72 hours | AS + HA North American routes | | Silver | 48 hours | AS + HA North American routes | **Eligible fares:** Economy (Y, B, H) and award tickets (E, P, T, N) **Outside the tier windows:** Saver fares (X class) are not upgraded on the schedule above **Companions:** Travel companions on the same reservation get the same upgrade priority ## Upgrade certificates What a certificate is, who can use it and how to apply one is on [how to use an Alaska upgrade certificate](https://2lnr.com/about/as/upgrade-certificates.md). What U class means, and which flights to target for it, is on the [Alaska upgrade strategy guide](https://2lnr.com/guides/alaska-upgrades.md). Earned as milestone reward choices at elite qualification thresholds. Certificates provide a confirmed upgrade path and can be shared with anyone. ### Key details - Offered as a Milestone Reward choice once you reach the qualifying status point milestones - Apply to Alaska and Hawaiian-operated North American flights - Shareable — the traveler doesn't need elite status - Confirm when U-class first-class inventory is available - Stored in your Atmos Rewards account wallet [Full certificate guide](https://2lnr.com/about/as/upgrade-certificates.md) ## Requesting an Alaska upgrade There is no upgrade request form to fill in for the complimentary path, and there is no way to jump the queue. What you can control is the fare you buy, the flight you pick, and whether you are holding a certificate when it matters. ### The complimentary waitlist Booking an eligible economy fare as an Atmos Rewards elite puts you on that flight's upgrade waitlist automatically. You can see the list in the Alaska app and on alaskaair.com under your trip, and it is also posted at the gate. Nothing is submitted and nothing is requested: the list simply processes at your tier's window and clears as far down as open U-class first-class seats allow. ### How upgrade priority is ordered Tier comes first: Titanium and Platinum are processed at 120 hours, Gold at 72, Silver at 48. Within a tier, Alaska orders the list by the standard tie-breakers, so two Golds on the same flight are separated by factors like fare and booking time rather than by anything you can ask for. Companions on your reservation inherit your priority and clear behind you. Applying a certificate moves you out of the waitlist entirely when U class is open, because a certificate confirms rather than queues. ### Paid first-class upgrades If you hold no status and no certificate, Alaska sells the seat directly. Buy-up offers to first class appear at booking, at check-in, and at the gate when seats are still unsold, priced by route and demand rather than from a fixed table. Whether miles can be applied toward an upgrade under Atmos Rewards is a moving target as the program transitions, so check Alaska's own upgrades FAQ in the Sources below before planning around it. ### Pick the flight, not the request Every path above ends at the same gate: open U-class inventory on that flight, on that date. Comparing two departures on the same route before you book beats anything you can do afterwards. Browse [every Alaska Airlines route](https://2lnr.com/routes/airlines/as.md) to see where the network goes, then track U class on the flights you actually want. ## Eligible flights Upgrade eligibility depends on the operating airline, not the marketing carrier. ### Operating carrier requirements - **Alaska-operated (AS):** All North American routes. First-class upgrades via U-class inventory - **Hawaiian-operated (HA):** All North American routes. Same upgrade mechanics as Alaska flights - **Partner-operated:** Not eligible for complimentary upgrades or certificates. Partner flights may have separate award availability **Track with 2LNR:** Select Alaska Airlines in the upgrade matrix to monitor U-class first-class availability across all AS-operated routes. Set up alerts to get notified when space opens. ## Sources - [Atmos Rewards: upgrades FAQ](https://www.alaskaair.com/atmosrewards/content/faq/upgrades) The program's own answers on how upgrades clear and which fares qualify.

Upgrades clear based on U-class first-class availability and your tier priority. Titanium and Platinum get a 120-hour window, Gold gets 72 hours, and Silver gets 48 hours before departure. **How do I request an Alaska Airlines upgrade?** For the complimentary path there is nothing to request. Booking an eligible economy fare as an Atmos Rewards elite adds you to that flight's upgrade waitlist automatically, and it processes at your tier's window: 120 hours for Titanium and Platinum, 72 for Gold, 48 for Silver. If you hold an upgrade certificate, applying it to the booking confirms the seat outright whenever U class is open, rather than putting you in the queue. With no status and no certificate, Alaska sells first-class buy-ups at booking, at check-in, and at the gate while seats remain. **Are Basic Economy fares eligible for upgrades on Alaska?** Not on the tier schedule. Saver fares in X class sit outside the upgrade windows, so they are not processed at 120, 72, or 48 hours the way other economy fares are. A regular Economy fare (Y, B, or H class) puts you on the normal waitlist, and award tickets (E, P, T, N classes) are eligible too. **How do I get a first class upgrade on Alaska Airlines?** Two ways, and both need U-class space open on the flight: a complimentary status upgrade, which clears inside your tier's window on an eligible fare, or an upgrade certificate applied to the booking, which confirms as soon as U is open and can be shared with someone who holds no status. ## Track Alaska upgrade availability Monitor first-class inventory on Alaska Airlines in real time.
