Aer Lingus-7
I posted this a couple of months ago so can I first apologise for posting it again as I got no response. And EI seem very reluctant to part with the information. They want me to ring them once I've booked and have a flight reference number but I'd rather know what I was facing in terms of getting an upgrade before I book.
I am Platinum Class now till November 2018. Two things if anyone can help. Is the complimentary upgrade to business class one way only? And when is it applied? At time of booking? Check in? Boarding? New to this loyalty program business so not sure. EI website and customer service not very good on this!
Thanks in advance for any help available.
