an airline that canceled your flight offers you an alternative flight that will reach your destination 14 hours later than your original flight. then the agent discovers a better flight that will get you there only 8 hours later, and you feel delighted. what persuasion technique is this?

The answer is contrast effect.

Explanation:

The constrast effect refers to the change in one's perception based on immediate comparisons. In marketing and investments, the technique consists in presenting two dramatically different alternatives, so that the customer has no choice but to accept the most convenient, and happily so.

This effect also applies to physical or sensorial stimuli (e.g. an object might feel lighter if you've previously carried a much heavier one).
