My boyfriend and I booked ambitious month-long trip from London to Istanbul and are almost halfway through, seeing the days away in Prague currently. We fly into Zagreb the day after tomorrow for a week in Croatia. Then we have about a week and a half before we need to fly out of Istanbul. One idea was to travel up to Sarajevo through Mostar, then catch a cheap flight to Istanbul. Any other ideas, suggestions? Thank you!
I would fly to Istanbul as directly as possible in order to spend more time in Turkey. Try www.skyscanner.com. There will definitely be a flight involved, whether or not you choose to go to Sarajevo, first. I'm not sure what the extent of flood damage is in Bosnia now, so enquire with travel agents or your other contacts in Croatia.
