Hey Queenbee..make sure you have all the important documents in your hand luggage and the chest x-ray. About your eticket, if its purchased via credit card you need to fill up a from since your bf is not travelling with you. Make him scan or photocopy the front and back of the card. Atleast that is what I know when my husband booked my flight but it was with Singapore Airline. My husband was travelling with me so we didn't have to go through all that paper work. Don't know if Cathay Pacific does that. It may help if you ring them on what necessary things you should do.

Have a safe trip and enjoy the Cold weather :!
