You will deal with the airline for any changes after departure.
This is only partially correct.
1. You will always deal with the TA, e.g. Expedia for any changes or cancellations, except:
2. Day of travel IRROPS. In this sole instance you deal with the carrier causing the delay, e.g. AC.
The problem with #1 is that TA's are stuck with the fare rules and are loathe to work outside them because an audit of an e-ticket may well lead to an ADM which they cannot likely recover from the passenger. On the other hand, carriers can be quite flexible, especially with their own metal. Moreover, you should carefully read any TA's policies as many impose their own fees and other conditions which are over and above the fare rules of the ticket and COC of the carrier.
