Mi madre siempre mira la pantalla para confirmar el origen y el destino del vuelo.

In Spanish, you normally need a possessive like mi if you want to say my mother.

• Mi madre = my mother
• Madre by itself would usually mean mother in a more general or literary sense, not specifically my mother

Also, unlike English, Spanish often does not use a capital letter for family words like madre unless they are part of a name or title.

Spanish often leaves out subject pronouns because the verb ending already shows who the subject is.

• mira can mean she looks, he looks, or it looks, depending on context
• Since Mi madre is already there, adding ella would be unnecessary

So:

• Mi madre siempre mira... = perfectly natural
• Ella siempre mira... = also possible, but only if you want extra emphasis or contrast

Mira is the third person singular present tense of mirar.

From mirar:

• yo miro
• tú miras
• él/ella/usted mira
• nosotros miramos
• vosotros miráis
• ellos/ellas/ustedes miran

It is used here because the subject is Mi madre, which is third person singular, and the sentence describes something she habitually does.

Siempre means always, and in Spanish it commonly goes before the verb.

So:

• Mi madre siempre mira la pantalla = natural and standard

You may sometimes see adverbs in other positions, but before the verb is the most common and safest choice here.

Both relate to seeing, but they are not exactly the same.

• mirar = to look at
• ver = to see

In this sentence, your mother is actively looking at the screen, so mirar is the best choice.

Compare:

• Mira la pantalla = She looks at the screen
• Ve la pantalla = She sees the screen

The second one sounds more like visual perception, not the deliberate action of checking it.

Yes, pantalla means screen, but depending on context it can also mean a display board or monitor.

At an airport, la pantalla could refer to:

• a digital screen
• a departures/arrivals display
• an information board

It is feminine, so it takes la:

• la pantalla

Spanish uses definite articles more often than English.

In English, you might sometimes say:

• She looks at a screen
• She looks at the screen

In Spanish, if the screen is understood or specific in the situation, la pantalla is very natural.

Here it sounds like a known screen, such as the airport display screen.

Para + infinitive is a very common way to express purpose in Spanish.

• para = in order to / to
• confirmar = to confirm

So:

• para confirmar = to confirm / in order to confirm

It explains why she looks at the screen.

This pattern is very common:

• Estudio para aprender. = I study to learn.
• Llamo para preguntar. = I’m calling to ask.

In Spanish, it is normal to repeat the article before each noun in a pair like this.

So Spanish prefers:

• el origen y el destino

rather than:

• el origen y destino

Both may be understood, but repeating the article sounds more complete and natural here.

Also, both nouns are masculine singular:

• el origen
• el destino

Because de + el contracts to del in Spanish.

So:

• de + el vuelo → del vuelo

This contraction is mandatory in normal Spanish.

Compare:

• el origen del vuelo = the origin of the flight
• el destino del vuelo = the destination of the flight

A similar contraction happens with a + el = al.

Because del vuelo applies to both nouns:

• el origen of the flight
• y el destino of the flight

Spanish often avoids repeating the same phrase when it clearly belongs to both items.

So this is efficient and natural:

• el origen y el destino del vuelo

You could repeat it, but it would sound heavier:

• el origen del vuelo y el destino del vuelo

Normally, it describes a habitual action.

That is because:

• the verb is in the present tense
• the adverb siempre strongly suggests a repeated habit

So the feeling is:

• My mother always looks at the screen...

Spanish present tense often covers what English expresses with the simple present for routines and habits.

Yes, depending on the nuance.

For example:

• comprobar = to check / verify
• verificar = to verify
• asegurarse de = to make sure of

But confirmar works well if the idea is that she wants to confirm the information is correct.

Possible alternatives:

• para comprobar el origen y el destino del vuelo
• para verificar el origen y el destino del vuelo

These are similar, but confirmar sounds very natural.

A broad Spain pronunciation would be roughly:

Mi madre siempre mira la pantalla para confirmar el origen y el destino del vuelo.

A few useful pronunciation points:

• ll in pantalla is often pronounced like the y sound in yes in many parts of Spain
• z does not appear in this sentence, but in Spain it would often sound like the th in think
• r in para and origen is a tapped Spanish r, not an English r
• v in vuelo sounds very similar to Spanish b

You do not need a perfect regional accent to say it correctly; clear vowels and the Spanish r matter more.

Yes, but the original order is the most neutral and natural.

Standard order:

• Mi madre siempre mira la pantalla para confirmar el origen y el destino del vuelo.

Other orders are possible for emphasis, for example:

• Siempre mira la pantalla mi madre...
  This sounds marked or literary.
• Mi madre mira siempre la pantalla...
  Possible, but less common than placing siempre before the verb.

For learners, the original sentence is the best model to follow.
