I use IFTTT with a project of mine[0] to track hotel and flight prices in a spreadsheet and get suggestions on places to go.

I have a few destinations I'm interested in and some others that I take regularly. I'm watching the respective airlines' own websites for specific searches, and gather the prices in a spreadsheet that I review every time I feel wanderlust.
Regarding the integration with IFTTT, I wrote about it here: https://blog.monitoro.xyz/post/190023685811/monitor-website-...
