Check-in boarding were all no hassle. Seat was bigger and cabin roomier than those of airlines owned by American companies. Arrival for connecting flight was 20 minutes later than schedule, but was able to board the connecting flight just in time. A female passenger who sat to my left, put up her feet on the back of her front passenger's seat, with her leg butterflied out. The other passenger to her left covered up his face (I think to avoid the sight of bare feet and butterflied legs. I endured this on an about 11 hour flight for a long while, and finally I walked up to tell an Asiana customer service staff. I didn't want to sit next to her until the unsanitary, inconsiderate and indecent postures were corrected. The staff finally went to talk to the female passenger and told me this was done. I would recommend customer service staff to walk the aisle and correct unacceptable postures of passengers.
