For now our TK flight is due to land at 3:45pm. The BA flight is due to depart 8:35am.
My plan is to stay at the Yotel landside just to be safe.
I'm sad not to be able to go into IST for dinner and an evening stroll but I've been there several times and I just don't think it is worth it,
I suspect we wouldn't be at the hotel until 5:30pm and pick up would be 5:45am.
Lanside gimes me the opportunity to check a bag. An option I would almost certainly not have with two separate tickets between TK and BA which would be a big problem using Yotel airside.
