Mañana volamos a otro país y tenemos que llegar temprano a la terminal.

Yes. Mañana can mean both tomorrow and morning.

In this sentence, it means tomorrow because of the context:

• Mañana volamos... = Tomorrow we’re flying...

If it meant morning, you would usually expect something like:

• Por la mañana = in the morning
• Mañana por la mañana = tomorrow morning

So here, mañana is understood as tomorrow, not morning.

Spanish often uses the present tense to talk about the near future, just like English does in sentences such as We’re flying tomorrow.

So:

• Mañana volamos... literally looks like Tomorrow we fly...
• but in natural English it usually means Tomorrow we’re flying...

This is very common in Spanish when the time is already clear from words like mañana, esta tarde, el viernes, etc.

You could also say:

• Mañana vamos a volar...
• Mañana volaremos...

But Mañana volamos... sounds very natural and common.

Spanish has several ways to talk about the future:

• Present tense: Mañana volamos
• Ir a + infinitive: Mañana vamos a volar
• Simple future: Mañana volaremos

All three can be correct, but they feel slightly different:

• Mañana volamos sounds very natural, especially for plans or schedules.
• Mañana vamos a volar can sound a bit more like an intended plan.
• Mañana volaremos is correct, but in everyday speech it can sound a little more formal or less immediate.

For flights, travel plans, and scheduled events, the present tense is especially common.

Because the verb already tells you who the subject is.

• volamos = we fly / we’re flying
• tenemos = we have
• llegar stays in the infinitive because it follows tener que

Spanish often leaves out subject pronouns like yo, tú, nosotros when they are not needed.

So:

• Mañana volamos... already clearly means
• Tomorrow we’re flying...

You could say Nosotros volamos, but it is usually unnecessary unless you want emphasis or contrast.

Because otro normally does not take un in standard Spanish.

So the natural form is:

• otro país = another country

Not:

• un otro país ❌

This is the same with many nouns:

• otro día = another day
• otra vez = another time / again
• otro problema = another problem

So a otro país is the normal and correct structure.

Because otro usually replaces the need for an indefinite article.

Compare:

• un país = a country
• otro país = another country

You do not normally say un otro país.

So otro already carries that indefinite idea of another.

Tener que + infinitive means to have to do something.

In this sentence:

• tenemos que llegar = we have to arrive

This is one of the most common ways to express obligation in Spanish.

Examples:

• Tengo que estudiar = I have to study
• Tienes que salir = You have to leave
• Tenemos que llegar temprano = We have to arrive early

It is very useful and very common in everyday Spanish.

Yes, it could.

• Tenemos que llegar temprano = We have to arrive early
• Debemos llegar temprano = We should / must arrive early

But there is a slight difference in feel:

• tener que usually sounds more like a real necessity or obligation
• deber can sound a bit more like duty, advice, or a somewhat more formal obligation

In everyday speech, tener que is often the most common and natural choice for have to.

Because the verb llegar normally uses a before a destination:

• llegar a casa = to arrive home
• llegar al hotel = to arrive at the hotel
• llegar a la terminal = to arrive at the terminal

So the pattern is:

• llegar a + place

This is just the normal construction of the verb.

Because after llegar, Spanish normally uses a, not en, to mark the destination.

So:

• llegar a la terminal = correct
• llegar en la terminal = not natural here

En is more about being in a place, not arriving at it.

For example:

• Estamos en la terminal = We are in the terminal
• Llegamos a la terminal = We arrived at the terminal

Spanish often uses the definite article more than English does.

Here, la terminal refers to the specific terminal relevant to the trip, even if it has not been fully specified.

So Spanish naturally says:

• llegar temprano a la terminal

where English might say:

• arrive early at the terminal or sometimes simply
• arrive at the terminal early

Using la sounds normal because both speakers understand which terminal is meant in the travel context.

Here, temprano is an adverb meaning early.

It modifies the verb llegar:

• llegar temprano = to arrive early

Compare:

• un vuelo temprano = an early flight
  Here temprano works more like an adjective.
• llegar temprano = to arrive early
  Here it functions adverbially.

In this sentence, it describes how/when they need to arrive.

Yes. Spanish word order is flexible.

Both of these are natural:

• Mañana volamos a otro país...
• Volamos mañana a otro país...

The version with mañana first puts a little more focus on the time:

• Tomorrow, we’re flying to another country...

Putting mañana at the beginning is very common when setting the scene for the whole sentence.

Because Spanish, like English, often links related actions with y:

• Mañana volamos a otro país y tenemos que llegar temprano a la terminal.

This sounds natural because both parts are closely connected:

1. we’re flying tomorrow
2. we have to get to the terminal early

You could split it into two sentences, but using y makes it flow naturally as one idea.

Yes, in this context it almost certainly means an airport terminal.

The word terminal can refer to different transport terminals depending on context, such as:

• bus terminal
• ferry terminal
• airport terminal

But because the sentence says volamos (we’re flying), la terminal is understood as the airport terminal.
