Yes. 여행 가방 literally means travel bag, and in natural English it often corresponds to suitcase or travel bag/luggage bag, depending on context.

• 여행 = travel, trip
• 가방 = bag

So this is a compound noun: a bag used for traveling.

You may also see 여행가방 written as one word. Spacing with Korean compound nouns can vary in real-life writing.

Because there are two different objects for two different actions.

• 여행 가방을 열고 = opened the travel bag
• 여권을 다시 확인했어요 = checked the passport again

So:

• 여행 가방을 is the object of 열고
• 여권을 is the object of 확인했어요

English learners sometimes expect one object marker for the whole sentence, but Korean can mark each object separately when there are multiple verbs.

열고 comes from the verb 열다 (to open) plus -고, a connector meaning and.

So:

• 열다 = to open
• 열고 = open and / opened and

In this sentence, -고 links the first action to the next one.

In Korean, when verbs are connected like this, tense is usually shown on the final verb, and that tense applies to the whole sequence unless context says otherwise.

So even though 열고 itself does not show past tense, the final verb 확인했어요 is past tense, so the sentence is understood as:

• opened the travel bag
• and checked the passport again

Both actions happened in the past.

Usually, yes. In this sentence, the natural reading is sequential:

1. opened the travel bag
2. checked the passport again

So -고 often works like and then in this kind of sentence.

However, -고 is a fairly neutral connector. It mainly links actions, and the exact nuance comes from context. Here, the order is very natural and obvious.

Because Korean often leaves out the subject when it is already understood from context.

English usually wants an explicit subject, but Korean does this very often:

• (저는) 여행 가방을 열고 여권을 다시 확인했어요.
• (그는) 여행 가방을 열고 여권을 다시 확인했어요.

Both are possible depending on context.

So the sentence does not itself tell you who did it; the surrounding conversation does.

다시 means again or once more.

So 여권을 다시 확인했어요 means the speaker checked the passport one more time.

It often corresponds to English again, but depending on context it can also have the feel of re- as in recheck.

Because 확인하다 means to check or to confirm, which is more specific than 보다 (to see/look/watch).

• 여권을 봤어요 = looked at the passport
• 여권을 확인했어요 = checked/confirmed the passport

So 확인하다 is the better verb if the meaning is about making sure everything is correct.

Also, 확인하다 is a very common Korean verb made from:

• 확인 = confirmation/check
• 하다 = to do

So literally it is something like to do a check/confirmation.

확인했어요 is in the polite, informal-style ending -아요/어요 in the past tense.

So it is:

• polite
• natural in everyday conversation
• less formal than 확인했습니다
• more polite than 확인했어

This is one of the most common endings learners should know.

Because Korean is generally a Subject-Object-Verb language, unlike English, which is usually Subject-Verb-Object.

A rough structure here is:

• 여행 가방을 = the travel bag
• 열고 = open and
• 여권을 = the passport
• 다시 = again
• 확인했어요 = checked

So Korean naturally places the main verb at the end.

Yes, 여행 가방을 열어서 여권을 다시 확인했어요 is also possible.

The difference is roughly this:

• -고 = simple linking, and
• -아서/어서 = often feels more connected, like after doing or sometimes by doing

So:

• 열고 sounds like a straightforward sequence of actions
• 열어서 can sound a little more like opening the bag was the step that allowed the next action

In this sentence, -고 is very natural.

여권 is pronounced roughly like yeo-kkwon.

A few pronunciation notes:

• 여 sounds like yuh
• 권 sounds like kkwon
• because of the consonant structure, it is not pronounced exactly as it looks to an English speaker letter-by-letter

Also, 확인했어요 is pronounced more like hwa-gin-hae-sseo-yo in actual speech, not in a fully separate syllable-by-syllable way.

Pronunciation often changes slightly from the spelling because of Korean sound rules.
