Have not really looked into this (and the pricing / availability to select dates in Aug/Sept)....
Curious if you folks who fly a lot more than I do think this is a good offer or not.
We understand that things can change at the last minute. That’s why we’re giving you the freedom to make unlimited changes to new tickets, at no extra cost.
For even more flexibility, we’re extending this offer to all new tickets purchased before 30 June 2020. You’ll also have more time to alter your plans, with free and unlimited changes available up to one year after your ticket purchase.
That means you can book knowing that you can push back your travel dates, or pick a new destination, as many times as you like.
