Interesting hearing that. At UAL we can’t reserve the JS so it’s actually considered a d-bag move to NOT list for both. JS is Cap’s discretion but it is seniority based unless there is an underlying reason why the Capt doesn’t want someone in it. IE Scab etc.

By listing for both, commuters have a better idea who is and is not JS eligible to be see the actual chances of getting on. Same goes for FAs.
