Hi Nathan75, I think you both should definitely be in business, and if you have the points 80000, spend them on your mum to be.
Otherwise for around $750 you can buy a standby upgrade, BUT do the figures first, as you may already be paying 1650, add another 1500 and you are close to an advance fare in Business.
Don't go right down the back, the tail kicks and sways, the pitch is less too, and the movement around the rear toilets is continuous through the night. bulkheads they will not release until the final moment awaiting basinet enquiries, leaving your first choice of exit seats as the best solution. If this is your final pick, ensure you take some ear plugs and eye shades, like the pack from business or you would be able to buy them at a chemist. I am sure with all these in/on you will have a good sleep.
If you need to save a few dollars, leave 24 hours later as the season changes, but I guess every man and his dog has booked the first week of the new prices. hope you had an enjoyable Christmas, regards bkkrop
