NB. AS is adding mainline service (A320) back to SEA-DAL in July. No U yet on the random days I checked.
Congrats! Particularly on finding U space in June....the August schedule seems relatively untouched and therefore a lot easier to find U space....now if you can find that elusive U space in July, let us know
