Want to Save on Flights? Can You Filter Specific Airlines?

So, I’ve been checking out a bunch of flight comparison websites like Skyscanner, Google Flights, Flightlist, and a few others. One thing that really caught my eye is the cool feature that lets you see how flight prices vary depending on the day or month you choose. For example, Skyscanner’s setup with the calendar view and bar chart is pretty neat. Now, here’s my current dilemma: I’m trying to book flights for me and another person from Frankfurt, Germany (FRA) to any airport in Tokyo (TYO), but I’m not trying to drop the price of a small used car on this trip.

I’ve come to rely on this feature that shows me the daily flight prices, but there’s one big thing missing as far as I can tell: the option to filter out specific airlines from these charts. Does anyone out there know of a website that offers those daily flight price charts like Skyscanner or Google Flights but with the ability to exclude certain airlines? The reason I’m on the hunt for this particular feature is that the cheapest flights from FRA to TYO are with Air China, which takes a route through Russia. Just like how some folks are uneasy about flying Boeing planes, even though the chances of something going wrong are pretty slim, I’m not too keen on flying over Russian territory.
