I subscribed to Scott newsletter/emails when I used to be based in the USA abd quite frankly his airfare findings are too good to be true. However, users shall expect these fares to be lasting hours as the respective airline would correct the mistaken fares as soon as its aware of its existence. due to the number of published airfares, planning could be difficult especially if visas are needed and whether it’s possible to take time off. Nevertheless, I highly recommend his newsletter if you are based in the USA as you will be introduced to endless opportunities.
