Yes. In 여권하고 탑승권을, 하고 connects the two nouns and means and:

• 여권 = passport
• 탑승권 = boarding pass
• 여권하고 탑승권 = passport and boarding pass

In everyday speech, 하고 is a very common, natural way to join nouns. Other possibilities are:

• 여권과 탑승권
• 여권이랑 탑승권

They all mean basically the same thing here, though the level of formality differs a bit.

In Korean, when two nouns are connected, it is very common for only the last noun to carry the case particle, and that particle applies to the whole phrase.

So:

• 여권하고 탑승권을
  means
• the passport and boarding pass as the object of the verb

You do not need to say 여권을 하고 탑승권을. In fact, that would sound wrong here.

All three can connect nouns, but they differ in style:

• 하고: very common, neutral, conversational
• 이랑/랑: casual, spoken
• 와/과: a bit more formal or written

So these all work:

• 여권하고 탑승권을
• 여권이랑 탑승권을
• 여권과 탑승권을

For this sentence, 하고 sounds perfectly natural.

가방 안에 means inside the bag.

Breakdown:

• 가방 = bag
• 안 = inside
• 에 = location/destination particle

So:

• 가방에 = in/on/to the bag
• 가방 안에 = inside the bag

Using 안 makes the location more specific. It emphasizes that the items should be put inside the bag, not just associated with it.

Because 에 marks the location or destination.

• 안 by itself means inside
• 안에 means in/inside

So in a sentence like this, 안에 is the normal form:

• 가방 안에 넣다 = to put something inside the bag

You will often see this pattern:

• 상자 안에 = inside the box
• 주머니 안에 = inside the pocket
• 서랍 안에 = inside the drawer

This is a very common and useful grammar pattern.

• 넣으세요 = please put it in
• 넣어 두세요 = please put it in and leave it there / please keep it in there

The pattern -아/어 두다 often means:

• do something in advance
• do something and leave it in that state
• keep something prepared

So here, 넣어 두세요 suggests more than just the action of putting them in. It implies:

• put them in the bag now
• keep them there so they’re ready

That nuance is very natural in travel or preparation situations.

Both are seen.

• 넣어 두세요
• 넣어두세요

In modern Korean spacing, auxiliary verbs like 두다 are often written separately, especially in teaching materials, because it makes the grammar easier to see:

• 넣어 두다 = put in and leave/keep

In real life, many people also write it 붙여서 as 넣어두세요. For learners, seeing it separated can be helpful.

세요 makes the sentence a polite request or instruction.

The base verb is:

• 넣다 = to put in

Polite command:

• 넣으세요 = please put in

With -어 두다:

• 넣어 두세요 = please put it in and keep it there

So 세요 is what makes the sentence sound polite and appropriate when speaking to someone respectfully, such as a passenger, customer, or guest.

It is grammatically a polite imperative, so it is closest to a polite instruction/request.

Depending on context, it can sound like:

• Please put your passport and boarding pass in your bag.
• Please keep your passport and boarding pass in your bag.

Korean polite imperatives with -세요 are often softer than English commands. In many situations, they sound perfectly courteous, not harsh.

Korean word order is flexible, but the most neutral order here is:

object + location + verb

So:

• 여권하고 탑승권을 = object
• 가방 안에 = location
• 넣어 두세요 = verb

A very natural English-like gloss is:

• Passport and boarding pass, inside the bag, put-and-keep please

You could also say:

• 가방 안에 여권하고 탑승권을 넣어 두세요

That is also natural. Korean often moves phrases around for emphasis, but the verb usually comes at the end.

Korean often leaves out things that are obvious from context.

In English, we usually say:

• Put your passport and boarding pass in your bag.

In Korean, if it is obvious that the speaker means your passport, your boarding pass, and your bag, those possessives are often omitted.

If needed, Korean could make it explicit:

• 여권하고 탑승권을 가방 안에 넣어 두세요 = natural, context does the work
• 여권하고 탑승권을 본인 가방 안에 넣어 두세요 = put them in your own bag

Omitting possessives is very common and natural in Korean.

Yes. 탑승권 is the standard Korean word for boarding pass.

Breakdown:

• 탑승 = boarding
• 권 = ticket/pass/document

You may also hear travel-related words like:

• 항공권 = plane ticket
• 승차권 = boarding/train/bus ticket depending on context

But for air travel, 탑승권 is the normal word for boarding pass.

Yes, that is a possible nuance, especially because of 넣어 두세요.

The sentence can suggest:

• put them in the bag for safekeeping
• keep them there so they are ready and not lost
• store them inside rather than holding them loosely

The exact nuance depends on context, but -어 두세요 often gives that sense of do it now and keep it that way.

Yes, 하고 can also mean with in some sentences. For example:

• 친구하고 갔어요 = I went with a friend

But here it clearly means and, because it connects two nouns that together act as the object of 넣다:

• 여권하고 탑승권을 = passport and boarding pass

So context tells you the role of 하고.

You could say:

• 여권하고 탑승권 가방 안에 넣어 둬.
  or
• 여권하고 탑승권을 가방 안에 넣어 둬.

This is casual speech and would be used with someone close to you, younger, or in a non-formal situation.

The original:

• 여권하고 탑승권을 가방 안에 넣어 두세요

is polite and much safer for learners to use in most public situations.
