Food not 2 goof

Can't fault EVA staff. Plane was delayed because of a passenger problem but rebooked connection at Bangkok efficiently and swiftly. 5 *

As Expedia has panicked me about my check in- it was a pleasure to deal with pleasant efficient check girl

Great flight, just a shame that it was late (again).

The international flight was delayed by an hour. This was dealt with very well in terms of the staff directing us to connecting flight 241 and flight 241 was held for us. However, our baggage did not arrive. It would have been helpful to be told at the beginning that our baggage would need to be sent to the hotel rather than us waiting for no reason. Also, my wife required gluten-free food. She had to skip 2 meals because there was no gluten-free option. We are not happy about that.
