The A346 was originally scheduled to return to LAX in early May, but that has recently been pushed back to May 30. Seems like the maintenance needed to reactivate the planes has taken longer than LH had originally expected. Of the four A346 routes, LAX is by far the trickiest to operate, as it requires 1.5 (so effectively two) frames, whereas the rest (EWR, JFK, BOS) only require one each.

Understandable, but disappointing nonetheless.
