Thank you all for the info!
Despite all the good things I read here about KLM, we will probably have to book with BA.
The KLM flight DXB-AMS STD is 07.00 LT, which means we would have to be in the airport arount 04.00 LT (KLM starts check-in 3hrs before departure).
We would have to leave our apartment at the beach around 03.00 LT.
With 2 children to get up and dressed, plus all the final things to pack (like the baby sheets, the baby bottles, their teddybears...), we would have to get up around 01.30, which is ridiculous.
A night like this as a start to our trip back home, would make it true hell!
If I would travel alone, without kids, I would certainly go for KLM... but in this case, BA's departure around 09.30 LT is far more acceptable I'm afraid...
