Ask Eva {% endhint %} Use this page for refund, schedule change, and operational follow-up questions. {% hint style="info" %} Submit Service Requests through Eva in ATRIP. {% endhint %} ### Do we get notified about schedule changes? Yes, but not always through a single channel.\ Airlines may notify the booking contact directly.\ Atlas webhook and incident flows should also be configured. ### Does Atlas guarantee webhook delivery? No.\ Webhook delivery is best effort. Use airline emails, incident flows, and order queries for final confirmation. ### How should post-booking operations be handled? Use Atlas APIs and ATRIP based on the action: * refunds and cancellations * ancillary add-ons * service requests for changes * incident follow-up ### Do you provide urgent post-sale support? For urgent cases within 24 hours of departure, use the airline’s **Manage My Booking** flow where possible. ### Where should we check refund and cancellation policy? Always use the airline’s latest policy as the source of truth. ### How long do refunds take? Atlas usually submits refund requests to the airline within 4 hours.\ Final confirmation and fund return still depend on the airline. After Atlas receives the funds, reconciliation and balance credit follow. ### How does Atlas void handling work? Use the dedicated void flow: * `voidQuotation.do` * `void.do` * `queryVoidOrders.do` Request quotation first. Then submit the void with the latest `voidOfferId`. Track status until the case is closed. See [Void](/api-document/product-guides/post-booking/void.md). ### Does Atlas support partial void for some passengers? No.\ Atlas accepts full-order void only. Do not submit void for only some passengers. ### What happens if we submit void after the deadline? Atlas rejects the request in real time.\ Typical message: * `Void deadline exceeded. This ticket can no longer be voided` If the void window has passed, re-check whether the case should move to refund. ### Is void quotation required when the void fee is fixed? Yes.\ `voidQuotation.do` is still required before `void.do`. ### How fast can we get a void result? In most cases, Atlas returns within about 5 minutes whether the void request was accepted for processing.\ Final completion or rejection can still take longer. Use webhook for progress updates.\ Use void query for final reconciliation. ### How should booking changes be requested? Submit a Service Request through Eva in ATRIP for name correction, flight change, or similar post-booking action. ### Are booking changes supported through API? Not as a general self-service API flow.\ Use Eva in ATRIP to submit the Service Request. ### How are involuntary changes handled? For airline schedule changes or similar involuntary cases, use the refund flow in ATRIP.\ This is handled free of charge. ### Can baggage or seat be added after ticketing? Baggage may be added after ticketing when the airline and order support it.\ Seat selection after ticketing is not supported. See [Seats](/api-document/product-guides/booking/optional-ancillaries/seats-and-baggage.md) for the current seat-selection support scope. ### What happens in case of booking or service failure? If Atlas causes incorrect booking or ticketing, Atlas will compensate with a replacement ticket when applicable.\ Refund delays remain dependent on airline processing. ### What support or training is provided for operations teams? Atlas provides a go-live walkthrough after UAT completion.\ That includes ATRIP process guidance and follow-up Q\&A. ### How does refund handling differ by payment mode? #### Deposit * Atlas tracks refunds initiated through Atlas * If the passenger or agency refunds directly with the airline, notify Atlas through ATRIP when required * Atlas credits your Atlas balance after airline funds are received #### VCC Refunded funds usually go back to the original VCC account.\ Do not use the ATRIP **Agent and Passenger Initiated Refund** flow for VCC refunds. ### What refund initiation options are available in ATRIP? #### Atlas-initiated refund Use either: * the **Refund** button * a **Cancel & Refund** service request through Eva #### Agency or passenger initiated refund Use either: * an **Agency & Passenger Initiated Refund** service request through Eva * batch upload in the refund module ### How should refund follow-up be handled? Wait at least 21 days after refund submission before follow-up.\ Then follow up in the existing service request through Eva, or create a new refund follow-up request in ATRIP. ### Related pages * [Refunds](/api-document/product-guides/post-booking/refunds.md) * [Post-booking](/api-document/product-guides/post-booking.md) * [Webhook Overview](/api-document/product-guides/extensions-and-integrations/webhook-overview.md)
