ETC extension DPs:

Used $147.15 ETC exp 3/5/24 and $20.00 ETC exp 6/4/24 to book Economy ticket for $156.38. Got leftover $10.77 retaining exp 6/4/24. Turned around and cancelled, got a brand new $156.38 ETC exp 2/14/25.

Encouraged by the success, I repeated the process for my other expiring ETCs.

Used ETCs $261.05 exp 3/5/24, $20.00 exp 6/4/24, $10.77 exp 6/4/24 and the new $156.38 exp 2/14/25 to book Economy ticket for $314.10. Turned around and cancelled, got $314.40 ETC exp 2/14/25.
