When you get no results for flights, it is generally because of two reasons:

a) There are no flights on that route for your dates

Some flights do not operate daily and others may not operate at all on that segment. You could try changing your dates, or provide your exact start and end location in the "Where from" and "Where to" fields and Blinctrip will find you another suitable route for your dates.

b) Technical difficulties

To rule out any technical difficulty, you could go to your browser history and clear the cache. This should address the problem when you try again.
