Jeg vil ombooke forbindelsesflyet.

In this sentence, vil is most naturally understood as want to / intend to.

Danish vil can sometimes refer to the future, but in a sentence like this, it usually sounds like the speaker is expressing a wish or decision. If you want to sound softer or more polite, Danish often adds gerne:

Jeg vil gerne ombooke forbindelsesflyet.

That is closer to I’d like to rebook the connecting flight.

Because vil is a modal verb.

After Danish modal verbs such as vil, kan, skal, må, and bør, the next verb normally appears in the infinitive without at.

So you say:

Jeg vil ombooke ...

not

Jeg vil at ombooke ...

This works much like English I want to rebook only with Danish modal grammar.

Yes. Ombooke is a normal and widely understood word, especially in travel, hotels, and customer service. It is a loan-based verb built from booke plus the prefix om-, which gives the sense of again / differently / מחדש in the sense of changing something.

So:

• booke = book
• ombooke = rebook

You may also hear other expressions, such as:

• booke om
• ændre min booking
• ændre min billet
• lægge min rejse om

But ombooke is perfectly natural.

It is a compound noun, which Danish uses all the time.

It can be broken down like this:

• forbindelse = connection
• linking -s-
• fly = plane / flight
• -et = the definite ending for a neuter noun

So forbindelsesflyet literally looks like the connection-flight, and idiomatically it means the connecting flight.

Compound nouns are extremely common in Danish, so this is a very useful pattern to get used to.

Because Danish usually marks definiteness by adding an ending to the noun.

For fly, the basic form is:

• et fly = a plane / a flight

The definite form is:

• flyet = the plane / the flight

Since fly is a neuter noun, its definite ending is -et.

That same ending stays on the whole compound:

• et forbindelsesfly = a connecting flight
• forbindelsesflyet = the connecting flight

A separate word like English the is usually not used in this kind of simple noun phrase.

Yes, if you mean my connecting flight.

There is a difference in nuance:

• forbindelsesflyet = the connecting flight
• mit forbindelsesfly = my connecting flight

When Danish uses a possessive like min, mit, or mine, it normally does not also use the definite ending in the same way. So:

• mit forbindelsesfly = correct
• mit forbindelsesflyet = not correct

Use forbindelsesflyet when the flight is already identifiable from the situation. Use mit forbindelsesfly when you want to stress that it is yours.

No. Another word you may hear is tilslutningsfly.

Both are understandable in travel contexts:

• forbindelsesfly
• tilslutningsfly

Also, forbindelse by itself often means connection, especially in transport. So Danish travel language often builds compounds from that idea.

For a learner, forbindelsesfly is very transparent and useful.

It is understandable, but it can sound a little direct.

In real-life customer service, Danish often sounds more natural with a softer phrasing, for example:

• Jeg vil gerne ombooke forbindelsesflyet.
• Kan I hjælpe mig med at ombooke forbindelsesflyet?
• Jeg vil gerne have ombooket forbindelsesflyet.

These are especially useful if you are speaking to staff at a desk or on the phone.

So the original sentence is grammatical, but in practice many speakers would choose a slightly softer version.

All of these can occur, but billet or booking can sometimes sound a bit more precise, because technically you are changing a reservation rather than the aircraft itself.

Natural possibilities include:

• Jeg vil gerne ombooke min billet.
• Jeg vil gerne ændre min booking.
• Jeg vil gerne ombooke min rejse.

Still, ombooke forbindelsesflyet is understandable and workable, especially if the specific flight segment is what matters.

A rough English-friendly guide would be:

Jeg ≈ yai
vil ≈ vil
ombooke ≈ om-BOO-guh
forbindelsesflyet ≈ for-BIN-nel-ses-fly-uh

A few important points:

• Jeg starts with a y sound, not an English j sound.
• ombooke has its strongest stress on the book part.
• In real spoken Danish, many sounds get reduced, so forbindelsesflyet may sound much more compressed than its spelling suggests.

For pronunciation, hearing native audio is much more helpful than relying only on spelling.

In a normal main-clause statement, yes, this word order is the standard one:

• Jeg = subject
• vil = finite verb
• ombooke = infinitive
• forbindelsesflyet = object

So:

Jeg vil ombooke forbindelsesflyet.

This follows the common Danish main-clause pattern where the finite verb is in second position.

If you move something else to the front, the finite verb still stays second:

Nu vil jeg ombooke forbindelsesflyet.

And in a question, the finite verb comes first:

Kan jeg ombooke forbindelsesflyet?

So the sentence is not random; it follows a very important Danish word-order rule.
