I was booking an upcoming trip and did a search through the app when I noticed some flight options were being duplicated.



On closer look, it’s not exactly duplicated as one option books under the AC codeshare flight number and one books under the operating carrier flight number.



Thought this was unusual as that does not happen (to my knowledge) on the website. The same search on the website just brings up the one option with an AC flight number on the codeshare segment.

This allowed me to book my flight from AC, but keep the operating carrier flight number, which then allowed me to use some ShebaMiles I’ve been wanting to offload for a SAUA on the segment.

Edited to note: Worked the same for the return segments too.
