Does anybody know of a website that gives reliable flight alerts for low fares?
Ideally, I would like it to :
- Be free
- Allow alerts on routes (ex. MXP - TXL), or from city to city (Milan - Berlin). If by city it is not possible, then allow multiple routes, so I can check all combinations of departure and arrival airports
- Compare all (or at least most) airline companies
- Send e-mails weekly
- Include return flights
Am I asking too much?
EDIT: With Skyscanner I think I can set alerts for a specific day, but I want to see when flights to a specific destination are at the cheapest, when does not matter.
