-## Payment & Transactions
-
-- [ ]  Add `CouponId` to `PayForTicketOrderAsync` in `IAccountService` & implementation.
-- [ ] Add `CouponId` to `TransactionDto` (adjusted to `CouponCode` later).
-- [ ]  Add `TopUpAccount` logic (DTO, Controller, Service).
-- [ ]  Add `Transaction` relationship to `TicketOrder` as one-to-one.
-- [ ]  Add logic for creating transactions with tickets.
-- [ ]  Add endpoint `GetMyTransactions` and DTOs (`TransactionDto`).
-
 ### ✅ Ticket Review & Confirmation
 
-- [ ] Add `TicketOrderSummaryDto`, map details: from/to city, company, vehicle, time.
-- [ ]  Implement `GetTravelOrderDetails` endpoint to fetch ticket summary.
-- [ ]  Display number of travelers, per-seat price, and total cost.
-- [ ]  Include coupon entry and balance payment option.
-- [ ]  Use ticket + person data (via `GetTicketOrderTravelersDetails`).
+- [ ] Make sure you have `TravlerTicketDto`, mapped to `` with the details
+```csharp

+- [ ] Implement `GetTicketOrderDetails` endpoint to fetch ticket summary, make sure to create required methods as well
