**Beta release**

This source is currently in **beta**. It works end to end, but you may still hit rough edges. [Let us know](https://us.posthog.com/#panel=support%3Asupport%3Adata_warehouse%3A%3Atrue) if you do.

The aviationstack connector syncs real-time, scheduled, and historical flight data along with aviation reference tables into PostHog, so you can analyze flight and aviation data alongside your product data.

## Prerequisites

You need an aviationstack account with an active access key. Some tables, such as historical flights and certain filters, require a paid plan.

## Adding a data source

1.  In PostHog, go to the [Sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section.
2.  Click **\+ New source** and click **Link** next to this source.
3.  Enter your credentials (see [Configuration](#configuration) below) and click **Next**.
4.  Select the tables you want to sync, choose a sync method and frequency, then click **Import**.

Once the syncs are complete, you can start querying this data in PostHog.

When linking Aviationstack, you'll need:

-   **Access key** – find it in your [aviationstack dashboard](https://aviationstack.com/dashboard). Note that aviationstack pricing is a monthly request quota tied to your plan.

## Sync modes

Each table can be synced in one of several modes, depending on what the source supports:

-   **Webhook** (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes.
-   **Incremental** – only new or updated rows are synced on each run, using a cursor field (such as an `updated_at` timestamp). Cheaper than a full refresh, but deletes aren't captured.
-   **Append only** – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs.
-   **Full refresh** – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected.

See [sync methods](https://posthog.com/docs/data-pipelines/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them.

This source is full refresh only. Every table is re-synced on each run because aviationstack has no server-side updated-at cursor.

## Configuration

| Option | Type | Required |
| --- | --- | --- |
| `Access key` | password | Yes |
| `Airport IATA codes` | text | No |
| `Days of future flights to sync` | number | No |

## Troubleshooting

-   If your access key is invalid or has been deactivated, generate a new key in your aviationstack dashboard, then reconnect.
-   If your plan does not grant access to a table, upgrade your aviationstack plan or deselect the restricted tables, then reconnect.
-   If you hit your monthly request quota, upgrade your plan or wait for the quota to reset, then resync.

If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](https://posthog.com/docs/data-warehouse/troubleshooting.md). If that doesn't help, [contact support](https://us.posthog.com/#panel=support%3Asupport%3Adata_warehouse%3A%3Atrue) – we're happy to help.
