Hi all, after some advice please. Just doing my visa application and from the UK to thailand and they want proof of flight and accommodation. As I will be trying for a repatriation flight I dont have flight and accommodation yet. What can I put in for the visa application?

I'm in the process of applying for a multiple entry tourist Visa on a UK Passport. I havnt booked a flight yet nor accommodation but it asks for both of these on the online application. Does anyone have experience of putting in the hotel I normally stay at and a date for flying but not actually use these. The reason I ask is I want to go to Thailand via USA and Korea and am flexible in dates or are they very strict and need proof of flight/hotel booking etc
