Given the task definition, example input & output, solve the new input case.
Given a travel related situation, and given a specific question about the situation, summarize the question into a title
Example: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

Output: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

New input case for you: I'm flying United from Melb to Mexico City, with a transfer at LAX. MEL=>LAX UA99, LAX=>MEX UA1077.

These were booked on "one ticket" (I believe I'm using the term correctly?), I paid United once and have a single itinerary describing all the flights.

I am now learning that the transfer time for these flight is perhaps tighter than I should have booked (1h45m). I have never travelled internationally before and just picked the one with the shortest layover.

According to step 5 here[1] I don't have to pass through customs, though I'd hardly say its a reliable resource.

This map seems to show UA exclusively limited to terminal 7/8 and apparently there is an "airside" inter-terminal connection between 6,7 and 8.

So I'm figuring that if UA99 lands at 7/8 and UA1077 departs from 7/8, then I can get off one plane, walk to the gate and get on the next, without any customs or immigration? I'm also carry-on only, so no bags to drop/collect/etc.

Is it reasonable to think that?

Relatedly, if I was to miss my connection due to immigration, delays, etc, would United rebook me to the next available since I booked "one ticket"?
