So...I survived the strike. My international bus got to Florenc at 11:30 pm. I tried to arrange an airport shuttle with a company posted upthread, but never received a confirmation so I decided to metro it.
I took Yellow to Green. At the second to last green stop the driver shut everything down after he said something in czech (this was at like 12:00:04 am). the drunk mexicans stayed on the train along with an old lady with eggs so I did too (i figured the lady understood what he said and didn't get off).
4 minutes later he continued to the last stop which was full of police, strikers, and press. I didn't take any photos because i wanted to make sure i caught the bus to the airport. It left right when i got to the stop, but per the schedule the next one came right at 12:28 am.
The cabs were all trying to convince us no buses were running, but the Spanish guy waiting with me said the newspaper said the airport buses were still running.
