How much does a business-class / lie-flat seat upgrade cost on a charter flight to Nha Trang, and how does the bidding system work?
Based on 1 discussion with 3 participants · Last activity: 21 days ago
TL;DR
Lie-flat seat upgrade prices fluctuate as the flight date approaches — bids can range from 16,000–20,000 RUB per direction, though groups sometimes negotiate down to around 40,000 RUB total; checking in late online risks getting seats far apart.
What the community said
A group of four negotiated a lie-flat seat upgrade on the return flight for around 40,000 RUB total; other passengers nearby paid differently — about 100,000 for outer seats and 150,000 for others (prices vary a lot flight to flight).

Without an upgrade and with late online check-in, seats can end up scattered — one couple got rows 14 and 26 on the return flight to Nha Trang (they sat together on the outbound leg), simply because they checked in near last and only leftover seats remained.

Upgrade bid prices for lie-flat seats drop closer to departure: about 4 days before a June flight, the bid was roughly 20,000 RUB each way, and the max bid was later lowered to 16,000 RUB; in May right after the holidays, prices were also low.
