LH will generally op-up OAL *G before LH*S (FTL - note that LH*G is the equivalent of UA 1K), and op-ups are more common on LH because they have far fewer free (including certificate) upgrades than UA. PE in particular is very commonly overbooked because the cabin is tiny.

That being said, you were still lucky
