the pre-boarding area in Manila to Vancouver is terrible. Not enough space. I was flying business and the seating that was reserved for this was not monitored therefore no seats available. Upon boarding for business the area was packed with passengers and no separate line for frequent flyers to board therefore we were stuck behind stanchions permitting us to board. We had to crawl or climb over the stanchions in order to board.... WHAT A MESS!! This criticism is not because I was flying as a frequent flyer as there is not this MESS when flying from Vancouver to Manila. Improvements must be made as this sets the impression for the rest of the journey.
