I’m looking to go to Poland in December. Had a look at flights this morning then again this afternoon and the price has gone up by £30! Is this because I am looking at them again and again? I have tried clearing cookies, private browsing etc but the price keeps going up! I don’t want to panic buy because the price has increased, my friend has advised me to leave it a few days and go back and look/book but does anyone think they’ll go back down or have I missed my chance at cheap flights?
