Giving back a DP:

Needed a flight from A to B on a specific date range that was more expensive than others.

So I found a flight between A and B on different dates that was within a difference of between $200-$250 of price of intended dates, then:

January 19:
- Booked A -> B on cheaper date range;
- Immediately after, changed tickets to the more expensive but intended travel date range

Charges to card: initial ticket plus "additional collection" for added cost of more expensive tickets

January 22: charges post

January 23: meter moves
January 23: later same day, -$200 credit posts
