Excellence’s Class booked and we had to wait 15 Hours when we could downgrade to an earlier flight. The logic makes No sense?

Excellence’s Class booked and we had to wait 15 Hours when we could downgrade to an earlier flight. The logic makes No sense?

Flight was ready to depart on time. We had a 20-minute ATC hold. We still landed on time. The landing seemed fast and rough.

Flight was delayed more than 1.5 hours. Essentially no communication with passengers regarding how long the delay would last or any updates as to the delay.

Clearer signage at Lisbon Airport and more communication about delays

Flight smooth and on-time. Food a joke, crew humorless but efficient. Really a budget airline masquerading as a flagship, but it gets you there.

Food is poor. Drinks in dixie cups, only white/red wine in Premium Prime despite business class food-which even that is a joke. Second “meal” on a 12 hour flight is a bagged sandwich in a cardboard box, which on premium airlines is a snack served BETWEEN meals. The premium economy product has some good parts but is obviously a cheap way of somewhat upgrading economy without actually putting any money into it. Lisbon airport is overcrowded and almost 3rd world as an airport. Crew is efficient but militaristic-crrtianly not “warm”. Entire experience feels like an intercontinental budget airline.

Overall ok experience as couple feedback: for improvement: 1. The vegetarian food was less and ran out, so many of us didn’t get it. Not all the crew member were polite and could be more hospitable.

No onboard entertainment or food, but that was okay because it was a short flight. Pretty much everyone just slept on the plane. The plane was comfortable enough.

The flight was excellent because I chose to upgrade to Business Class. The only negative drawback was because I upgrade, it screwed their system up and they lost my luggage for 2 days, but it was then recovered.

Web site needs improvement Plane was clean and modern Lay Flat beds were hard and not to comfortable (business class )

For my first experience flying, I was blown away with the service, the flights and staff

We boarded late; there was a problem with passengers that I believe TAAG could have handled much better. The Crew Handled it Excellentely but TAAG was not able to resolve the issues instantly and led to a 2 hour delay

The scheduled departure was delayed 9 1/2 hours and then delayed another 45 minutes due to baggage or something. Apparently the return flight is delayed 10 hours also, which means I miss my Lufthansa flight out of Luanda. Perhaps this is a scheduling change for which people were not notified until the last minute.

I did not receive any confirmation email of this booking and only on receiving it 24 hrs closer to the flight - I tried to cancel it as I has already booked another flight

Short lay-overs and total flight times. Everything else could have been better.
