They lied about baggage costs My flight on scoot from blr to Singapore was 2 hrs delayed and no reason

SIN
Okay 4.3

Early alert that flight was going to be 5 hours late.

No online check- in. Very slow check in at airport. Vouchers provided for food at airport - only problem was we couldn’t find a place that would take them. Boarding was painfully late and slow. As we arrived in the early hours of the morning the cost of taxis were double the normal price. Still no compensation as promised by the airline when they initially advised us of the late flight. Could do a lot better.

We arrived safely.

I was unable to check in online.When I mentioned this at the ticket counter the agent responded that they kept hearing that from passageners. Apparently this wasn't enough of an issue to make any changes. The plane was uncomfortable for such a long flight. Lots of movie choices, but few current choices. Flight attendants weren't that friendly.

Transfer was handed well between domestic and international terminals, but not a moment to spare. Cabin crew was attentive and highly professional. The announcements were handled well. Will fly them again!

In Guangzhou there was just enough time to transfer between flights. If there had been a delay, I would have easily missed the connection. The connections at Guangzhou involve multiple gyrations of shuttles between terminals and immigrations, etc. There was an opportunity to upgrade the cabin while boarding, but was not well announced or implemented. I would have welcomed the chance to upgrade.

The crew was really nice, saw them help several people put their luggage in the overhead bin.

There was absolutely no complimentary service at all, a bit unusual compared to flights we've taken in the past (domestic and international). No offer of free water, what's up with that?!?! There was no entertainment on board for an overnight flight, no blanket, no pillow. And on top of that we paid too much to check in a bag when we arrived at the airline desk because we didn't include it through our Kayak booking. Had we known there was a method to follow, we would have to avoid the excessive fee.

I get the seat selection pre-check in is a premium service. Bu to not allow someone to express preference (based on what's left) when they check in is downright snarky. The explanation that I got that "we need to balance the plane" is whitewash. It's clearly to push peopel to buying the premium service. But when you do that at the price of alienating people, you've done them and yourself a disservice. Time to rethink!

Very attentive and pleasant stewards in business class. Boardjbgblrocedures good.

We had to climb up stairs to get on the plane. There were elderly travelers who struggled to carry their hand luggage. No help was offered This needs to be remedied. Food also was not too palatable. Could be better Difficult to understand English of the announcements. Also when delayed in landing no announcements made br the captain though we were hovering in the air for 45 mins.

No one to assist my friends enter the plane. No one to help with hauling minor carryon baggage up the outdoor staircase. Very difficult and no offer at all for anyone in a party of six to help. No lift and no one offered assistance in business class to help at all.once on the plane service was outstanding. Passengers in 70s and 80’s and no knowledge of the need to to climb stairs and without any assistance. Attendants watched the elderly struggle.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

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

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
