I'm being offered business class for a ticket with HKG-SGN and HAN-HKG in February.

The email says lie flat seats. Do VN A321s have lie-flats? The flights are only suppose to be 1.5-2 hours each way. According to Seatguru, the VN A321s have 16 business class seats with "10 recline" with 45 inch pitch and 21 inch width. So probably not lieflats

Optiontown is offering $200 total for both ways (I'd paid $305 in Sept.).

The main items of interest for me would be:

1. Better baggage allowance, including carryon items. I think the weight limit for Y is like 7 kg?

2. Fast Track Security and Faster Immigration - "Enjoy faster security checks and save your precious time" and "Enjoy faster immigration service." This is the wording on the email but when I click through, I can't find anything on the Optiontown site about these.

Does Faster Immigration means I can jump the queue for getting my Visa on Arrival letter stamped?

3. "Gourmet meals and drinks" - I don't know how good VN soft product is, especially in their business class.

Really the first two might be worth it if it saves me time and avoids hassles.

Anyone familiar with these features, greater baggage allowance on VN and faster immigration and faster security checks at SGN or HAN?
