Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.
