Good day, I will be traveling from USA to Istanbul airport. My flight leaves from Denver and I have a connection in Frankfurt Germany. I will arrive in Istanbul around 1730. My question? I connect in Istanbul and travel to tunis tunisia but, I have to go and collect my luggage and recheck it into Tunis air because I had to buy two separate tickets. I have 5 hours and I hear that this airport is difficult to navigate. I do have a Turkish visa. Can I please get some advise on the best way to make this as uncomplicated as possible? Thank you in advance!
