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

Q: Take for example this flight:

in 45 minutes you have to go through immigration, security checks, and probably you need to go to a different terminal: it's basically guaranteed that you can't catch the connecting flight

If I lose this connecting flight, are airlines required to find a replacement flight to me? (possibly without charge)

A: If security checks during a layover take too long time and I lose the flight, would the airline find me a solution for free?

Q: Upon entering India with an e-Visa (formerly known as tourist visa), the immigration agent writes the expiry date of the visa on the printed e-Visa (not the one on the passport, but the one we're supposed to print from the e-visa website). Does one have to keep the printed e-Visa on which the immigration agent wrote the visa expiry date?

Q: 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?
