Seriously, they want us to believe they decorated the C cabin of a A359 in PEK like that and coincidentally had that many kids on board that happen to terminate in HEL.... puhlease...

Travelling in Business Class next week and got the pre-departure e-mail. I usually never bother to read it, but this time I did. My bolding.
I'm confused now.
Pre-ordering champagne is for Y travel, I suppose?
And pre-ordering meals is not possible when clicking onto the link. Do they mean special meals or regular meals?
Enjoy champagne and chocolate on board
Treat yourself by pre-ordering champagne and chocolate for your flight.

If anyone wants to know how to validate a AY+ number, some genius working for AY made it public. I am not familiar with this algorithm so for educational purposes why not discuss it here:
Ninth digit is the check digit.
From the rest of the 8 digits, make a sum of the odd positioned digits as they are and add to it each of the even positioned digits multiplied by 2,2 and truncated.
Take 200 and substract the sum
Do modulus 10 (ie find the left over after a integer divsion with 10). You now have the check-digit which should be equal to the ninth digit.
Or, with digits named n1 through n9:

Code:
n9 == ( (200 - n1 - n3 - n5 - n7 - (Math.floor(2.2 * n2)) - (Math.floor(2.2 * n4)) - (Math.floor(2.2 * n6)) - (Math .floor(2.2 * n8))) % 10)

Nothing super secret about it... the Luhn algorithm is a widely used checksum: https://en.wikipedia.org/wiki/Luhn_algorithm

Also, do note the subtraction (200 - sum)

I did a test and it seems to have the same weaknesses as Luhn (won't detect some twin errors like 33 -> 66)
So it works much like a normal Luhn, but produces a different check number. Can't really find a reference to this algorithm so what is why I thought it was designed to obfuscate the check digit calculation.
