# eta(request) Retrieves estimated arrival times to up to 10 destinations from a single starting point. ``` eta(request: EtaRequestOptions): Promise; ``` ## Parameters `request` An [`EtaRequestOptions`](/documentation/MapKitJS/EtaRequestOptions) object that specifies details for the server to provide estimated arrival times at one or more destinations. ## Return Value A promise that resolves with an [`EtaResponse`](/documentation/MapKitJS/EtaResponse) on success, or rejects with an `Error` on failure. ## Discussion To get a set of estimated arrival times, provide an [`EtaRequestOptions`](/documentation/MapKitJS/EtaRequestOptions) object when you call the [`eta(request)`](/documentation/MapKitJS/Directions/eta) method. You can provide up to 10 destinations. The server returns an error if you request more than 10 destinations in a single request. Pass an `AbortSignal` from an `AbortController` to the [`signal`](/documentation/MapKitJS/EtaRequestOptions/signal) option to allow the controller to cancel a pending request. When the controller aborts, the promise it returns rejects with a `DOMException` whose `name` is `"AbortError"`. --- Copyright © 2026 Apple Inc.
