I have a couple of TATL reservations where the return was not used because of Covid-19.
I couldn't rebook online and when I called, the agent had to spend a long time talking to the rate desk.
Turns out that if it has been more than a year since the outbound, the tickets have to be repriced using a special "more than one year" fare, which comes to some ridiculous price (eg between $3k and $4k for a W fare).

Obviously at these fares it would make sense just to abandon the return, but was just wondering if others have had the same experience or if this is one of the HUACA situations ...
