I take this chance to wish you a great trip.
In addition to the good advice already given on booking the best seats, I suggest that you log on to the Cathy Pacific website - http://www.cathaypacific.com/cpa/en_GB/homepage - as your top priority on Tuesday at 12.30 pm!
• Click on “ Manage Your Trip “ then from the drop down menu “ Manage My Booking “
• Select the button for “ Non-Member of Marco Polo Club / Asia Miles
• Enter your name exactly as booked, together with either Booking Reference Number OR eticket Number ( which presumably you already have, and should have printed in duplicate for security)
• Select button for Hong Kong flight ( and then repeat for Manila flight )
• Click on “ My Details “ then “ Seat/Other Services “
• You should be able to book your chosen seats for both these flights at the same time.
• The reason for booking your seats as soon after 12.30 pm as possible is that you will get the best choice of seats which are still available. Seats with extra legroom will not be available ( unless you pay about 75 GBP extra for each flight ) . Similarly new Premium Economy seats have been recently fitted on some of the Cathay Pacific Long Haul flights to Hong Kong – they are the best but only available at a premium of at least 600 GBP. Once you have booked your seat(s) you can print your Self-Print Boarding Pass or send Mobile Boarding Pass to your mobile device for the flight to Hong Kong.
Good luck.
