I love this forum and have had loads of great advice over the years which I have been so grateful for.
I often see people mention how they have got hacks for various aspects of travel - flights, hotels etc.
I spend hours looking at skyscanner air b&b trivago but don't think I have developed any hacks.
What specifically do people do?
I'd love to know or are they closely guarded secrets. ( can understand why they are obviously!)
