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

Example Input: My question is inspired by this one: Japanese etiquette: Most common (and offensive) mistakes? Which made me think about my upcoming trip to China. 

As a Dutch citizen, I have experienced a lot that what we consider normal behavior, is considered rude or absolutely not-done, in other, even bordering, European countries. I've not been in Asia before, but I am prepared to try to adjust to the local customs as much as possible, and I think there is a lot that can be done wrong.

I've read the linked question with great interest, but I wonder to what degree these answers will actually apply to China? 

For example, I recently learned that when toasting, you show respect by keeping your glass lower than the other.

Example Input: A few days ago I wanted to buy Pegasus airline tickets because it was offering a 50% reduction on normal fares. I wanted a few tickets but couldn't even buy a single one. I tried different places with different networks but none worked. I even called my sister in New York to buy tickets for me and the result was again ineffective. 

This is not the first time I encountered this problem. I have faced similar issues with other budget airlines as well (Ryanair, AirAsia). All the time during the sale, the website page was unresponsive. Well I do understand it all happens because of airline biggest sale promotion. I have bought promotion tickets "buy 1 get 1" and "Up to 25% off" before, but never been able to buy anything from the biggest sales.

Is there any possibility or hack to buy an airline ticket in one of these sales?

Example Input: 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.

Example Output:
