# Exchange process

## General workflow for ticket exchanges in TCP

This article contains a high-level overview of the exchange process in TCP. Further details about different types of exchanges can be found later in this guide.

1\. **Retrieve/Open the PNR**, validate that it contains the details about the originally issued ticket and that the e-ticket is still open for use. The itinerary must be modified already (alternative dates and/or flights selected, changes saved).

2\. **Select the ticket for Exchange/Reissue and select Exchange Option.** TCP supports 4 possible scenarios: 

| Exchange Option                  | Description                                                                                                        |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| Exchange using new fare quote    | TCP fare quotes the new itinerary                                                                                  |
| Exchange using stored fare quote | TCP uses fare quote for new itinerary already stored in the booking file                                           |
| Involuntary change               | To use in case of involuntary exchanges                                                                            |
| Exchange using manual fare quote | Use in cases when it is necessary to store the fare calculation created manually but without using cryptic entries |

3\. **Review fare calculation details** and **Select Penalty type:**

* EMD
* To the fare (Q surcharge)
* Tax
* No Penalty

4\. **Select *****Issue ticket*** to complete the exchange process and issue a new ticket, or *Go to PNR* to save changes into the fare quote and issue a new ticket later.
