That didn't matter for me recently. On a site, flights in cart, looked at rental car for <5 minutes and the outbound flights jumped ~$60/ticket in that time "due to demand" when the flight was 80%empty...

Got on my phone, on data (so new browser, new IP) still prices are higher. Hopped on my old phone over VPN to change region, checked out a different leave date, checked a couple, went back to my original date and flights were $40 cheaper (so still $20 more than before) but they gotta know based on Geo IP and time of inquiries it's probably all the same person, smh.

What a scam!!
