I want to travel to Poland in a month or so to visit sick relatives. Like the title says, I'm an Epileptic and to stay safe I can only travel during waking hours. I go to bed at 10pm every day. I live in Chicago so what I've always done is travel to London, England during a day flight, spend the night to start adjusting to the time, then travel on to Poland from there. For the return, I buy a direct flight from Krakow to Chicago leaving at noon and arriving at 3pm local (10pm for me since I'll be on Polish time). The problem comes up that I buy this as a multi-city ticket when using an online page and cost really racks up because of that first night I have to spend in London. I think they treat it as a separate trip. Last time I had to do this the tickets alone cost me more than $3,000.
Any advice on how to save money here would be greatly appreciated.
