Food hope it make it international not mainly like pilipino food

Just a little improvement on food but everything is excellent

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

This was actually a bus ride to the KW airport. It was smooth and comfortable and on time.

The plane in use lacked an entertainment system (perhaps because it was still being updated?). It was an overnight flight so it wasn't terrible but still. The actual seat was adequate but not great. As an economy flyer, food review is largely irrelevant. I am unhappy with this race to the bottom for services provided especially as it applies to baggage restrictions.

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

Good flight, friendly crew and overall - good service on United Airlines.

Enjoyed the flights with Air Canada. Friendly, courteous staff and flight crew - kept us informed and efficiently got us boarded and to destination on time. Seats were reasonably comfortable and good room in the overhead spaces.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

In flight WiFi not working. entertainment system not functioning Food was mediocre poor for business class Service was ok but not excellent Crew were pleasant. Announcements were made at a ridiculous volume.
