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

Ex Input:
I'd like to see the Catacombs of Paris in September 2017. It appears that tickets can be purchased in advance from http://b12-gat.apps.paris.fr/accueil.aspx ... is the demand such that purchasing tickets in advance is necessary if you want to see it?

I'm currently enrolled at Victoria (by TAP). Even though I collected new miles over the holidays, my old miles will expire.

What other Star Alliance programme would extend the expiry date of all my miles without extra charges?

Note that this is the case with FlyingBlue (by KLM): my miles would expire in February, but with the new miles I collected over the holidays, all my miles have a new expiry date. Thanks.

EDIT: This list shows a number of airlines that allow free resetting of expiry date, although it doesn't split the airlines by alliance.

Ex Output:
Star Alliance programme with free expiry date extension

Alright, the story is simple. I don't have a valid PR card with me, my new card will arrive by mail to my apartment in Montreal. A friend will mail it to me. Tomorrow I'm travelling

MONTREAL -> NEW-YORK -> SAN-FRANCISCO

So, will United demand to see my PR card (which I don't have), or will they let me leave? I don't know if this is important but I have a B1/B2 visa to travel to the USA.

I have read their site about document requirements, but the formulation is ambiguous. Any tips?

Thank you for your time.
