I will compare around skyscanner, expedia, sometimes expedia got great combination of flight and hotel at super cheap price. I bought before to HCM taking SQ for around 5 days during Christmas with hotel around 500+ sgd. I went KL flight and hotel (good one) 100+sgd.

3rd party is a pain and expensive if need to make any changes.

Usually from a consolidated platform for the first screening

Flights: direct from airline Hotel: airbnb or third party

Direct website for flights, booking.com for hotels

I love to use Skyscanner to get the best deal

I use booking.com or expedia or tripvisor...

Third parties cannot be trusted la too shady

More options and I earn loyalty points too

Have not tried third party site before
