Okay 4.3

Pros: We had to come home 2 weeks early due to the virus, and Singapore airlines were brilliant at changing the flights. Even got upgraded to the extra leg room for free

Cons: The extra leg room seats were naff, I like getting comfy in a chair and these ones were not. The screen was too far away and the arm rests didn’t move. Also, due to my partner having to swap seats, I was sat on my own next to strangers. They slept the whole way, so the crew never disturbed them meaning I missed out on food and drinks, even when asked

Pros: Crew was super nice and the food was good (for plane food)! Really appreciated that they had snacks and chocolate on hand for hungry passengers throughout the flight. A 17 hour plane ride is never the best, but Singapore Air made it as pleasant as possible. Also, we booked on Kayak and was routed through a third party vendor JustFly, which I was a little worried about - but our booking went off without a hitch.

Cons: Nothing really too bad, you get what you expected. May of been nice to have a free sandwich as it’s a non stop flight - this is because Lufthansa has one stopover and offers a free sandwich and drink.

Pros: Check in was simple and efficient, boarding was easy, leg space was sufficient, air hostess where polite and plane was clean prior to take off. Landing and take off both on time.

Cons: Two toilets for 100+ people meant long queues for the bathroom throughout the flights. The toilets were not even once cleaned in a flight of 4 Hours, meaning that by the final hour, they were a complete utter disaster in terms of hygiene. Pilot made a complete mess of descending and landing.

Good 7.0

Pros: The crew is not so amazing and the food is not so good.They only serve pork and sea food..i don't eat those food for my religion and i asked for another food anything as long as i had something for im starving, for they never had another food to give? You mean i cannot have food while boarding the plane? Im starving and they don't gibe us any food to eat even if i asked them if theres anything . And that is a total not agreeable we are 3 people riding the plane myself and my kids and we did not have anything to eat. The crew is rude when I asked something instead of looking for another food is theres any. I paid for my flight including the food and i was not able to eat.

Cons: Crew serving food should be nice and make sure that all passengers have food to eat especially if one, two or three or more doesn't eat pork and shrimp..if only i could i could transfer plane at that moment i will do it. Hope they will not feel the way i feel i was starving the whole flight..

Cons: They fed us expired food. Expired ice cream and expired yogurt. They could not put my wife and me together and I believe that it violates a new law passed by Senator Chuck Shummer. It made it difficult for me to get her medicine to her. On a short flight it wouldn’t matter as much. But we had to endure it for 15 hours. They only fed us two meals instead of 3. Other airlines put a sticker in front of you if you slept through the meal time.

Excellent 9.0

Pros: A great flight with friendly staff, comfy seats, good food, and great inflight entertainment.

Cons: The international transfer process at Manila airport was the worst I’ve ever seen. They had about 20 people standing at a desk for about 90 minutes with no explanation as to what was going on. In that time, nobody was released to go to their gate, but they wouldn’t explain what was happening. There were about 10 airport staff standing there, mostly doing nothing. The process was inefficient, to say the least. There was no place to sit, no toilets, no order to any of it. In most international airports, after you deplane, you just walk to your next gate. There seemed to be no logical reason for that awful experience. It would have been much faster to go through customs and then go through security, walking directly to the gate.
