I was fortunate enough to fly quite a lot of A380s with different airlines!
Twice with EK CDG-DXB and then 777s to Colombo.
Once from JNB to LHR with BA in the upper private economy section at the back of the deck - one of the best cabin I have ever been in as a Y traveller on a Euro 300 return CDG-JNB (fantastic value at that time).
Around ten times in EY A380 Economy Cabin.
Whilst in Europe or at least in France points earning credit cards are non-existent, apart from the AF Amex card, I am slowly building my points stash on different programs.
Etihad is for me the best cabin for a Y traveller.
In the beginning, when they were not charging for seats, you could choose your seats at the beginning of the deck in the small cabin with the stairs where J and F passengers are going. This cabin is the best, so much legroom, usually extremely quiet and you do not hear the engine.
The aircraft is super clean, IFE Is fantastic, and I do prefer them to EK where it's a bit too much everywhere.
As I only fly with EY when I am going to Europe two or three times a year, I have been able to maintain my Gold status with them and now am Platinum. I am always very excited when I can fly comfortably and still have a flawless experience, from check-in, to lounge access, seats and food.
Flew them from Melbourne, Sydney, Paris and London in A380s and Hong-Kong, Brussels and Francfort in 787.
I flew with them on my birthday, and I was fortunate enough to get a cake and a card from the crew. I know it's nothing crazy, but the intention was there, and that was a pleasant flight.
I am relatively young and pleased with how I am always well treated when I fly EY. Fantastic with VA when you arrive from your long flight from Europe.
I am quite attached to those two airlines as they were the airlines I flew before moving to Brisbane, so might be a bit biased.
Never had the luck yet or enough points to fly J/F internationally, but this will come, one day!
Hopefully we will be able to fly again an A380 soon enough.
