EY is great airline in terms of hard and soft onboard products BUT their ground service is truly SHOCKING.
As one of their CSMs onboard said: "Their mentality is, go to work do the bare minimum and go home". It is very true, they just don't care about the pax, it doesn't matter if you fly Y or F, if you're a nobody or EY Gold member, everyone get the same treatment.
On a recent flight BNE-MEL-AUH-LHR-TXL my luggage was lost somewhere between BNE and AUH. EY blamed QF and vv. Bottom line while staying in AUH I tried to reach EY for help but nothing, they couldn't care less. QF on the other hand (the P1 team to be accurate) kept me updated with phone calls and emails twice daily.
EY customer service is very bad, staff not well informed and they don't let you speak with supervisor! Baggage services at AUH airport never answer the phone so there is no one who can help and provide updates. When I asked them to call me back with updates was told customer service can't call overseas numbers and they don't send emails regarding baggage issues so there is basically no way to know when the luggage will arrive. The only way to get an idea is via WorldTracerWeb which is far from being an accurate source.
When finally arrived to Berlin I thought great, now I can deal directly with AB. German airline should have better customer service right? Wrong! Their baggage service was even worse!
In conclusion, EY are great, as long as all goes to plan.
