Remember if u wanna leave the airport in turkey, u must get a visa before, thanks to my stupid travel agent that didn't tell me that & I was stuck in the airport for 6 hours
Sorry bro, but it's not a travel agent's responsibility to tell you whether you need a visa or not in order to leave the airport on a
connection. A
stopover (24 hours or more),
maybe... but on a six hour connection, definitely not, especially if you don't even ask.
And especially in a country like Turkey, where 90% of frum Jews would be too afraid to leave the airport, I can't imagine why it would even occur to your TA to even dream that you might want to leave, if you don't ask them about it.
