Find direct flights to specific airport for specific date (from any departure airport)

Bear in mind that aggregators won't necessarily carry all providers or all flights. So the best way to get a definitive answer is to do the following:

• First, assuming the destination airport is a reasonably well-known one, try Wikipedia to get a list of airlines and their destinations from that airport. E.g. Tenerife North, Tenerife South, Santa Cruz de La Palma. Often the airport's website also has this information, or at least a list of airlines servicing it.
• Cross-reference those with where you want to travel from. In this case, Tenerife South shows a number of Scandavian flights with Norwegian Air Shuttle.
• Use that airline's website to determine whether it meets your requirements.

It's not quite as nice as RoflcoptrException's answer (and I'd probably recommend using that myself as an initial step), but for a definitive answer for a general case this works well.

You sound exactly like the type of person we have developed our new travel search engine Glooby for.

There is no doubt that air travel emits a lot of carbon dioxide emissions from planes that affect our environment. Since there are over 1 billion international tourists every year, I understand that you are trying to minimize our environmental impact as much as you can when flying.

We have developed a travel search engine, helping environmentally conscious travelers like you find the most fuel-efficient flight. Simply enter where you want to go and which dates, and let our search engine help you compare prices on airline tickets. We search among a variety of travel agencies, airlines and booking sites and show you all the information you need to make better travel decisions.

If you’re just looking for direct flights, just search and choose ”direct flights” in the filters. But besides just comparing prices, we also calculate carbon emissions from every flight and automatically show the most fuel-efficient flights first in the search results. So you don't have to do everything yourself.

When calculating the flight carbon footprint we use a formula that takes into account flight distance, if the flight is non-direct with stopovers or direct-flight, fuel consumption per aircraft type, number of seats in airplane, cabin class etc. You can read more on our website.

So besides just showing direct-flights, you will also be able to choose the most fuel-efficient aircraft (coming soon) for example, fuel-efficiency differences by choosing an Airbus 340 or a Boeing 787. Where we take into account flight timetables for example.
