Been staring at a exJapan DONE3 (i think) for the past week. finally pulled the trigger today for a starting flight in 2 days from Tokyo-HKG first before onwards to London.

Did booking on OW website. When I was playing around with TOK-LHR as first leg before, was not able to pay on the website and instead asked to call into BA Japan office to pay. However as I wanted to add the Tok-HKG leg anyhow I did that and a payment field came up. Finally put in payment dets and pulled trigger about 6 hours ago and got a confirmation email with reservation code and saying an eticket will follow. Haven't yet received that eticket and I haven't seen my card charged

Any vets here know how long it usually takes? I see the first few legs of the flights show up on my marco polo account used on the booking, but as payment not processed (there was a 0.01 usd charge from Cathay) and i havent received an eticket I am a bit paranoid given I am supposed to fly out in 2 days.

Also, if i were to want to make changes to this ticket, who do I call or contact?
My schedule is only certain for the first few legs and last few, in between i could be changing stops.
