Flight scrape

• Saves the kayak link into the Details Link - whereas this should be used for the GVA.CH scrape
• Duplicates seem to still being produced (eg if you run the scrape a second time)
• Doesn't seem to detect or save the airline code.
  • Plus airlines have created a bunch of blank airlines (linked to flights - ie can't delete)
• Does scraping make more sense, as the airline is shown in the drop-down?   https://www.justfly.com/
