Singapore Airlines' regional business class seat review on Singapore-Kolkata route
Consensus Summary
Both articles review Singapore Airlines' regional business class on the Singapore to Kolkata route (SQ516), highlighting its lie-flat seat design on the Airbus A350-900, which is narrower (20 inches) and less spacious than the airline's long-haul business class (28 inches). While the concept of a fully flat bed on a 4-hour 20-minute flight is praised, reviewers note discomfort due to the firm mattress, awkward footwell geometry, and lack of a mattress topper or full turn-down service. The SilverKris lounge at Changi Airport is described as pleasant but crowded, and the baggage allowance is generous. Food quality is strong, with a multi-course meal including a vegetarian Indian option, and the cabin crew maintains Singapore Airlines' signature attentive yet unobtrusive service. The review also mentions the airline's sustainability efforts, including SAF partnerships and a net-zero emissions goal by 2050. The regional business class will extend to a new route from Western Sydney starting November 23, 2026, with a late-night departure. Both sources agree the product is a mixed bag, offering innovative features but falling short of long-haul comfort, earning a rating of 3.5 out of 5 stars.
