I like that they have food on the way to Singapore but it’s only one package of food nothing else. I didn’t like that the gate number on the boarding pass is different from the announcements at the airport there’s no consistency, the same thing happened on the way to the Philippines on June 3 with Singapore airlines flights delayed & different gate numbers on the boarding when I got to the gate number.
