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

Example Input: I am in Europe and my wife is in South America. I'd like to buy her a flight ticket to her to come here. I am not going to fly with her. The most affordable ticket is Condor's but, according to their "Live Chat" person, I can only buy that ticket with a Credit Card even though I could buy using Debit Card from their payment system. 

So, I am bit confused if the person who answered me was confused as well.

Does anyone here ever bought a ticket for someone else [in Condor]? 

Example Output: How to buy a flight ticket for someone else in Condor?

Example Input: My minor daughter is traveling by herself internationally, leaving from Boston's Logan airport.

It's the first time she's traveled via air on her own, and I'd like to go with her to her gate (past security) to make sure she doesn't have any hassles.

I've seen some indications that it's possible to do this, but I've not had any luck figuring out how to do it.

Is this possible?

If so, how? Do I need the airline to OK it? TSA? Someone at Massport?

Closed, and the dupe helped me.  The airline is United, and they explicitly say on their website (I was missing the key phrase "gate pass" in my searches):

Example Input: My partner and I are planning a long (2+ months) trip to China. The return date is unknown in advance. We may also want to visit other countries on our trip and ideally would prefer not to commit to returning directly from China.

We're considering whether to buy a 1-way plane ticket to Beijing (and buying the other way when we know from where and when) or an open-ended or cancel-able round-trip ticket.

Of these options - or others we haven't considered - which would be most practical in terms of:


Cost? Flexible tickets tend to be more expensive.
Visa requirements? We may need to present evidence that we actually plan to leave China.
Flexibility to change our plans. Are open tickets fixed to the departure airport? What about an open-jaw, open-date return flight?


This related question has general advice but I'm interested specifically in the visa requirements of China: What is the best method of purchasing a ticket with an open return date?
If it matters, we're coming from Tel Aviv, Israel.

Example Output:
Is an open-ended ticket more practical than a one-way ticket for touring China?
