instruction:
Given a travel related situation, and given a specific question about the situation, summarize the question into a title
question:
I have a refundable ticket taking me from 'A' -> 'B' and then 'C' -> 'A'. However, I have now made further plans, so that I do not need the C -> A ticket anymore. So, given the limited travel budget that I have, I'd like to have the return / final leg of journey refunded.

The cost of the total flight was less than the one-way tickets from A -> B would be now, so it does not make sense for me to cancel the entire itinerary. I'd like to travel on the first leg, and have the second leg refunded if possible.

p.s. I am not getting off at any layover. The flights from A->B and C->A are more than 15 days apart and I have my own ways of traveling from B->C independent of the airline.

answer:
Can I have the final leg of a multi-city flight refunded?

question:
Is there any day of the week and time when airfares are statistically the cheapest to buy?
I read this question, but does anyone know it specifically for Qantas?

Particularly, I'm searching for a flight from Sao Paulo (Brazil) to Auckland (New Zealand).

answer:
When is the best day and time to buy tickets at Qantas?

question:
I'm planning to have a trip around in Peru and I was wondering if I can just reserve the hostels on the day I arrive in a new city or if I should call them a few days before. I'm traveling in April.

I can also try more than one hostel, of course I need to arrive before evening in each new location.

answer:
Peru: Can I reserve the hostels on the same day I arrive in a new city?
