Thanks. I will do a more thorough search of the forum again, though I tried for a good 15 mins to find, without luck.

I would indeed rather leave it to the crew (it was the first time I attempted it as normally the kids love to sit by themselves, and I thought I would be able to crack it!) but this particular crew last weekend did not know.

It's a fine balance between the risk of breaking a finger and be ejected from a flight as the kids don't want to sit alone. Last week out of embarrassment I would probably have gone for the broken finger!
