Given a travel related situation, and given a specific question about the situation, summarize the question into a title
One 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?

Solution is here: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Explanation: 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

Now, solve this: Two days ago I flew with KLM from Calgary to Germany, first with the "Dreamliner" 787 and then with the 737 in economy class. I had the impression (due to my impaired space during eating on the 787) that the seats in the 787 are narrower than in the 737.

Is this true or just my imagination?
With the distance between the seat rows I am not so sure. Maybe reduced too?

Solution:
Are the Seats in the Boeing 787 narrower than in the 737 in KLM Airlines?
