United857

I don't know if this is a glitch or not, but for N2644U on the UA889 on 3/5, the seat map shows no PE again despite showing PE on the previous flight for UA888 on 3/4.

EDIT: Looking at the 2 flights following the UA889 on 3/5, UA837 on 3/6 and UA78 on 3/7, it does seem to have been a glitch as those later flights are once again showing PE.
