LHR
Good 6.0

Pros: Decent service.

Cons: I paid 100$ for my seat, for more leg room. It happened that the seat next to me was unoccupied. I thought it would give me an opportunity to stretch out a bit to sleep on the Atlantic crossing. Another passenger's tv didn't work so one of the stewardess told him he could sit next to me. He got more leg room for free. I was cramped and could not sleep because of muscle spasm. The Legal age made it more comfortable but it is not worth 100$

Pros: Got the seats I wanted, movies were good. Staff was friendly

Cons: In Montreal they took my carry on bag stating it was too big, I have traveled with it many many times and it always fits except the tiny planes, this was a 787. When I got on the plane many people had larger bags then mine and it was the last bag on the carousel at the other end.

Good 6.3

Cons: at last minute itinerary was changed.. instead of routing through Brisbane, was now routed through Sydney. Flight from Sydney to LAX was delayed by 4 hours, then missed flight LAX to LAS... overall long delayed arrival. Checked the route through Brisbane, and those flights we're all there, departed and landed all on-time... so wondering what the reason was for the change of the itinerary without a cause (no cancel or delayed flights through Brisbane)

Good 6.0

Pros: The flight itself was fine and the crew was excellent. The boarding process was efficient.

Cons: My center seat, which was assigned, put me in an extremely uncomfortable position physically for the entire 14 hour flight. My two seatmates extended physically into my space, and minimal legroom meant by knees were pressed against the seat in front. I was not happy at the lack of seat choice.

Pros: The boarding was fast.

Cons: For starters our cabin crew were the worst. The first service I had ask for a snack and no napkins. Dinner service was like just chucking food down in front of you. Then a stewardess looks me dead in the face and passed me for the drink service, then she said she thought I was asleep.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
