# Delta Air Lines on the pay layer: the 360 agent-readiness check

In short

Delta Air Lines scores 13 of 100 on Ora's agent-readiness scan, an F, read 14 Nov 2026. The six payment checks did not apply to delta.com on this read, which is how Ora treats a site it does not read as a shop. A read that got no page back, on the lowest score among the sellers here.

On 14 Nov 2026 the public site at delta.com scored **13 of 100** on [Ora's](https://ora.ai/?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=check) agent-readiness scan, an F, in Ora's Travel & Hospitality category. Delta Air Lines is the largest airline in the world by revenue, so this check reads the Payments layer first: the six checks that look for x402, MPP, UCP, ACP and AP2 on the domain, the same protocols this site's matrix tracks row by row. The other layers follow, with every check Ora ran and what it saw. Ora's one-line summary: Turns agents away at the door: no MCP server, no OpenAPI spec and no public API to call.

## The score

| Layer | Points | Share | What the layer asks |
| --- | --- | --- | --- |
| Discovery | 4 of 9 | 44% | Can agents find and recommend it |
| Access | 0 of 33 | 0% | Can agents read it |
| Usability | 3 of 50 | 6% | Can agents use it |
| Payments | 0 of 0 | none apply | Can agents pay |
|  |
| Total | 13 of 100 | 13% | Grade F |

## The pay layer

Ora did not run the six payment checks against delta.com on this read: it marks them not applicable on a site it does not read as a shop, so the layer has no maximum and costs nothing. A travel seller that sells online can still publish any of the five protocols; the matrix says which processors and platforms carry each one. Each protocol links to its matrix row, where the processors and platforms that carry it are dated and sourced.

| Payment check | Result | Points | Matrix row | What Ora saw |
| --- | --- | --- | --- | --- |
| x402 | Does not apply | 0 of 2 | x402 in the matrix | No x402 payment protocol support detected. No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| MPP | Does not apply | 0 of 2 | MPP in the matrix | No MPP (Machine Payments Protocol) support detected. No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| UCP | Does not apply | 0 of 3 | UCP in the matrix | no UCP (Universal Commerce Protocol) signals detected. No commerce signals detected - agent-payment protocols are optional for non-commerce sites |
| ACP | Does not apply | 0 of 3 | ACP in the matrix | no ACP (Agentic Commerce Protocol) signals detected. No commerce signals detected - agent-payment protocols are optional for non-commerce sites |

## The other layers, check by check

Every check Ora ran on delta.com, grouped by layer, with the result, the points and what Ora recorded where its wording passes this site's gate.

### Discovery: 4 of 9

| Check | Result | Points | What Ora saw |
| --- | --- | --- | --- |
| ARD discovery | Fail | 0 of 1 | No /.well-known/ard.json, no same-site rel="ard" link, and no legacy /.well-known/ai-catalog.json |

## The fixes worth most points

Ora attaches an estimate to each failing or partial check: how many points the site would gain by passing it. These are the 5 with the largest estimates for Delta Air Lines.

Developer resource discoverability

Fail, 0 of 4, about 9.9 points to gain. Ora saw: In a search for your API docs, none of the 10 results is your official docs.

MCP server / manifest

Fail, 0 of 10, about 8.9 points to gain. Ora saw: No MCP server or manifest found.

OpenAPI spec published

Fail, 0 of 8, about 8.1 points to gain. Ora saw: No OpenAPI/Swagger specification found.

Public API with reachable endpoints

Fail, 0 of 8, about 7.1 points to gain. Ora saw: No publicly reachable API surface detected (REST and GraphQL both absent or auth-gated).

WebMCP support

Fail, 0 of 8, about 7.1 points to gain. Ora saw: No WebMCP support detected - no document.modelContext / navigator.modelContext usage found.

## Our read

Delta's 13 is the lowest score among the sellers read here, and most of it is a read that never started: Ora's request for the home page got no page back, the agent user agents could not be tested and robots.txt could not be fetched, so the door, content, policy and structured-data rows are unverified and the Access layer reads 0 of 45. Ora found no commerce signals, so the six payment checks did not apply on this read, on the airline with the largest revenue of any in the world. What could be probed came back empty: no publicly reachable API, neither a developer portal nor an OpenAPI specification, and neither an MCP server nor OAuth discovery. A search for the API documentation returned no official page in ten results, 6.7 points, and the brand search placed delta.com sixth for a word with other meanings. Whether the airline rate-limited the scanner or turned it away is for a second scan; the act layer is empty either way.

## Test your own checkout

The scan above is free and needs no account: enter a domain at [ora.ai](https://ora.ai/?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=check) and read the same layers for your own site, with the six payment checks mapped to this matrix on [the Ora Payments page](https://agentreadycheckout.com/method/ora-payments-layer). The command below runs the same audit from a terminal and exits with 1 under the score you set, so it can gate a deploy.
