Not sure what is going on but earlier today I had a booking confirmation from P&O for our December 2015 cruise. OK I thought just another one of P&O's computer "glitches"

as I had already had a booking confirmation back in April when we booked the cruise.
Anyway just out of curiosity I thought I would compare the two booking confirmations and found the following:
- The price has been reduced by £142 per person

- We have an additional £100 OBC per person

- The arrival back in Southampton date has changed by one day so we now arrive back one day earlier but the number of nights is still the same
- The cruise does not appear on P&O's website

Looks as if there was a "glitch" with the calculations so we have been reduced by the £142 and the extra OBC is compo - all fine by me as I was only expecting to go for 24 nights anyway.
