What does なら mean in 空港へ行くなら?

Here なら sets up a condition or topic-like assumption: if you're going to the airport / if it’s a case of going to the airport.

It often sounds like the speaker is responding to an already relevant idea. So compared with a plain conditional, なら can feel like:

• If you’re going to the airport, then...
• As for getting to the airport, then...

It is less about a purely hypothetical condition and more about taking a situation as given and commenting on it.

Why is it 空港へ行く instead of 空港に行く?

Both へ and に can be used with 行く.

• 空港へ行く focuses a bit more on direction toward the airport.
• 空港に行く focuses a bit more on the destination.

In many everyday sentences, the difference is small, and both would be natural. Here へ is perfectly normal.
