It’s missing a “not American, what are these ‘MQD’ things you speak of?” checkbox.

Also, looks like it doesn’t handle upgrade scenarios - my booking was a paid G, MUAed into OY. Flight experience and privileges (check in, lounge, etc.) are Delta One, but AIUI earning is still G-based. Tried entering -DL.OY- first but it just ignored the whole segment.

Would also be cool if it integrated code from pnr.sh to optionally fetch/autopopulate some information where applicable.
