My flight is estimated to depart around 11:20. I don't really know at what time I'll get to Gatwick, but I guess an hour and a half or two hours later.
If I don't show up, my celular phone is +351 962 453 400 (OK, if by any chance you need to contact me, that's the number).
I'll probably be in the social meeting tonight... wherever that may be... :-)
