Back in November, I waitlisted some PE flights back from Europe for Summer 2019. One waitlist shockingly cleared within 24 hours, while another one just cleared yesterday. I didn't bother looking for business awards though.

A bit off off topic, how many waitlisted PNRs can one have under manage my booking? Also, if a waitlisted flight clears, is it still possible to add another segment to it when you ticket?
