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

Example Input: I'm looking to travel by train from Lucerne to Montreux in Switzerland.

sbb.ch gives me two main options:

Via Bern, in 2.5 hours: route map
Via Neuchatel, in 3 hours: route map

Is the latter significantly more scenic? If not, I will choose the faster route.

Example Output: What is the most scenic route from Lucerne to Montreux?

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 have recently traveled to Lisbon and almost each day while being there I have received the same message thorough a cell-broadcast channel on my mobile phone:

21 Lisboa

I have asked my host, but she did not know what this message meant. I am thinking it might be related some weather warnings, but the worst thing I have endured was a light rain.

Question: What does "21 Lisboa" cell broadcast message mean?
