Regarding boosting flights, I want to book and boost a return ticket for December 2019 , so let's say I book it, then boost it, then aim to get 6 or more goals up to a max of 13 goals (for the 100% discount on base fare).
What if I were to book a different return ticket for October 2019 whilst still boosting the above, can I decide to stop boosting the December return ticket at any point in time and then start boosting the October 2019 return ticket?
Is this possible with an end result of having boosted 2 return tickets and being paid back respectively on the number of boosted goals met for each one?
