When I know the airline, the flight number, and the airport at each end, but am very flexible with dates, how can I find the cheapest flights?
In my case the airline will be Aeromexico, and it would be from Shanghai, China to Tijuana, Mexico, and the flight numbers are AM98 and AM99.
But the dates could be pretty much anywhere from August 2016 up to six or even more months later than that.
In my case I'd be spending up to a year mostly in China and nearby Asian countries and taking a side trip to Mexico for a couple of months at some time within that, based on when prices are as low as I can find.
But I'm looking for a general technique that anybody could use to find flights.
I've tried Adioso, Momondo, and SkyScanner but they're all very inflexible and incapable for this kind of thing, unless I'm missing something.

What does flexible dates mean for flights?
Flexible flights are those which allow for changes or cancellations after the purchase has been made. By purchasing a flexible flight, also known as flexi flights or open tickets, travelers are able to change travel dates or even cancel last-minute for no fee or a smaller fee than with regular airline tickets.Where can I find cheap flights with open dates?
Click here to search on Skyscanner. Skyscanner lets you see a month of fares at a time, which can save you a bundle if your dates are flexible. It will also let you see the cheapest month. To see flights for a whole month, or choose the cheapest month, just click in the Depart box.Do airlines use same flight numbers on different days?
Airlines can schedule multiple flights with the same flight number on the same day (sometimes on the same route and sometimes on different flight segments). This varies by carrier.How do you get the cheapest flights?

Answer 2
You can use google flight for this
https://www.google.de/flights/#search;f=SHA,PVG;t=TIJ;d=2016-08-01;r=2016-09-25
Click on the Start Date and then click on the Price Graph.
You could give a start date (1st Aug) and a duration (55 days). Then the price graph would give all possible sliding windows of length 55 days starting from 1st Aug.
Answer 3
Try with Kiwi. I have written about Kiwi in my answers here and here.
You can not specify the flight numbers but you can specify the origin and destination as well as direct flights only which for your case of AM99 and AM98 boils down to the flight numbers you were looking for.
Datewise, you can specify a date range of several month for both departure and return or a duration of stay of 2-31 days. The cheapest I get for departing August - September 2016 and staying 2- 31 nights is EUR 1079.
Funnily the graphics of Kiwi make it look like you were not flying over the Pacific ocean but the other way round :)
Answer 4
Like the above person said, only be totally inflexible on the times you're willing to fly out and land. Specifying the airport (not choosing "all airports") and specifying the airline couldn't hurt, either.
