  • If you have to finish off that last piece of work before your flight don’t worry, London Heathrow has Plaza Premium lounges in Level 4, Terminal 2 Departures where you can pay around £30 to enter and then take advantage of the private work pods and Wi-Fi, allowing you to concentrate on sending out those last few emails.

Very nice, I feel I got good value for the price.

Amazing one of the best airlines i have ever traveled with. I live with medical issues called psoriatic arthritis and was in pain on the flight. The flight crew made sure I had fresh ice pack ever hour. Going above an beyond with service and care ⭐️⭐️⭐️⭐️⭐️.

Overall is good. But Asian movie selection was not great at all. And also more snack food to give out

Don’t preorder the diabetic meal if you don’t have to. Whoever creates those meals thinks everyone loves fish, and hates seasoning. In a world where we can find diabetic friendly candy and low card bread, it’s surprising that places are still serving flavorless gelatin and rice cakes. Boarding in Taipei was chaos. They tried to form a line but didn’t manage it. So once the gate was opened, the line didn’t matter and everyone just mobbed to the front.

We were very impressed with the modern plane its amenities, as well as the services of flight attendants.

I had knee surgery a few weeks prior. I was using cane walking very slow. Crew were extremely helpful

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Seats. there's no way to go to the washroom when you’re seated in the middle without bothering the person beside you.

Service in BKK was very good at answering our question about our canceled flight from Taipei to San Francisco. Did like the lead time about the canceled flight from Taipei to San Francisco and was not given the best options.

EVA! What is going on with your food!?!? Pre pandemic I used to go to Taiwan at least twice a year and always flew EVA — the food was consistently tasty for airplane food. Post pandemic, it’s not great at all. Step it up!
