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: Last time I visited the UK,
it took 3 hours to get through the immigration queues.

I recall seeing signs saying something like:

"Registered Travellers from [list of countries] can use the EU/UK lines."

I have another trip the the UK in a few months,
and I am really dreading the giant queue, especially after a 17 hour flight.

So I am looking up how to become a Registered Traveller.

It says:

Apply online for Registered Traveller membership. ...
You'll get a decision on your application within 10 working days. ...
If your application is accepted, the next time you travel to the UK you must go through the 'other passports' lane and fill in a landing card.
The immigration officer will check that you meet the criteria and tell you if you can become a member. ...

So does this mean that being accepted at point 2, isn't a real acceptance.
You get the real acceptance the first time you enter after applying, using the 'other passports' lane (i.e. the non-UK/EU line).
And then after that if you visit the UK again (assuming all successful), you get to use the EU/UK lane?

(I mostly just want to know if I am understanding it right. I think other things mean it just isn't financially worth it to me to become a registered traveller. I'ld need to pay for a Visa since I've not visited 4 times before)

Output:
Is it possible to use UK/EU lanes as a Registered Traveller the first time you enter the UK after applying?
