Fare Class Differences
So there's 2 parts to this question, but I'm posting it together to avoid cluttering the board :P I'd appreciate if people could answer both, but the first one is the more important one.
1) Premium Economy vs Tango
How much "better" is premium economy than Tango? % wise... so I can judge whether it's worth it to fly PE vs Tango on a YYZ-HKG flight (amongst others)
The PE fare for YYZ-HKG seems to be almost double the Tango fare. ($1800 vs $1000)... is it worth it? How much more would you pay for PE vs Tango?
2) Flex vs Tango
Flex doesn't actually look more flexible than Tango. And it's a lot more expensive (sometimes same price as PE)
Why do people book flex? Is it because of the ability to upgrade, the extra miles, or something else? If the miles, isn't it an expensive way to get miles?
