Am Flugsteig warten wir auf den Anschlussflug.

German often puts a time/place expression first to give it emphasis or set the scene.

So:

• Am Flugsteig warten wir auf den Anschlussflug.
• Wir warten am Flugsteig auf den Anschlussflug.

Both are correct.

The difference is mainly focus:

• Am Flugsteig first = emphasis on where
• Wir first = more neutral, starting with who

Because German is a verb-second language, if Am Flugsteig comes first, the conjugated verb warten must come second, so wir comes after it.

Am is a contraction of an dem.

• an dem Flugsteig → am Flugsteig

This is very common in German.

Examples:

• am Bahnhof = an dem Bahnhof
• am Fenster = an dem Fenster

In this sentence, am Flugsteig means at the gate.

German uses different prepositions depending on how a place is viewed.

• an often means at, by, or on
• in means in/inside

A Flugsteig is thought of as a point or area at the airport gate, not something you are really inside of in the same way as a room or a building. So am Flugsteig is the natural phrase.

So:

• am Flugsteig = at the gate
• im Flugzeug = in the airplane

Because it is a noun, and all nouns in German are capitalized.

Here the nouns are:

• Flugsteig
• Anschlussflug

This is one of the most noticeable spelling differences between German and English.

Flugsteig is the standard German word for an airport gate or boarding gate.

However, in real life, many German speakers also simply say Gate, especially in airports.

So these are both possible:

• am Flugsteig
• am Gate

Flugsteig is good standard German, but Gate is very common in everyday airport language.

Anschlussflug means connecting flight.

It is a compound noun:

• Anschluss = connection
• Flug = flight

German makes compound nouns very often, so learning to spot the parts is very useful.

Other related words:

• Anschlusszug = connecting train
• Flug = flight
• Flughafen = airport

Because the verb phrase is warten auf and auf here takes the accusative case.

The noun Anschlussflug is masculine:

• der Anschlussflug = nominative
• den Anschlussflug = accusative

So:

• Wir warten auf den Anschlussflug.

This is not about movement here; it is simply the fixed pattern warten auf + accusative.

If you mean to wait for someone/something, yes, you normally use warten auf.

Examples:

• Ich warte auf den Bus. = I’m waiting for the bus.
• Sie wartet auf ihre Freundin. = She’s waiting for her friend.

If you just say Ich warte, it means I’m waiting, without saying what for.

This is different from English, where wait can directly be followed by for. In German, the preposition is part of the normal pattern:

• warten auf + accusative

German usually uses the simple present tense for actions happening now.

So:

• Wir warten can mean:
  • we wait
  • we are waiting

German normally does not need a special continuous form like English are waiting.

That is why warten wir is perfectly natural here.

Grammatically yes, but the meaning changes.

• auf den Anschlussflug warten = to wait for the connecting flight
• den Anschlussflug erwarten = to expect the connecting flight / to be anticipating its arrival

For people physically standing at the gate, warten auf is the most natural choice.

So in this context:

• Wir warten auf den Anschlussflug is better.

Because the first position in the sentence is already occupied by Am Flugsteig.

German main clauses usually follow the verb-second rule:

1. first element
2. conjugated verb
3. the rest

So here:

1. Am Flugsteig
2. warten
3. wir auf den Anschlussflug

If the subject comes first, then it looks more like this:

• Wir warten am Flugsteig auf den Anschlussflug.

Yes, it is correct and natural.

A few very common alternatives are:

• Wir warten am Flugsteig auf den Anschlussflug.
• Wir warten am Gate auf unseren Anschlussflug.
• Am Gate warten wir auf den Anschlussflug.

The original sentence sounds slightly more written or textbook-like because of Flugsteig, but it is still perfectly good German.

A rough English-style guide is:

• Anschlussflug ≈ AHN-shloos-flook

A few notes:

• schluss sounds like shloos
• flug rhymes roughly with loog, but with a shorter vowel
• the ch in Anschluss is not like English ch in chair; here it is part of the sch sound = sh

And Flugsteig is roughly:

• FLOOK-shtyke

But pronunciation guides are only approximate; listening to native audio is best.
