は marks 友達 as the topic of the sentence: as for the friend...
Here, the sentence is telling you what happened with that friend. If you used が instead, it would sound more like you are identifying or emphasizing the subject: the friend is the one who...
So:
- 友達は... = As for the friend...
- 友達が... = The friend is the one who...
Both can be grammatical, but は is the more natural choice here for a plain narrative sentence.
で marks the place where an action happens.
In this sentence, the action 見送る happened at the airport, so you say:
- 空港で見送る = to see someone off at the airport
A helpful comparison:
- に often marks a destination or point of existence
- で marks the location of an action
So here, the airport is not the goal of 帰る; it is the place where the seeing-off happened.
