This page gathers the essentials for flying with Donghai Airlines: official website, fares, online check-in, baggage rules and customer service contacts.

Since its founding in 2014, Donghai Airlines has grown into a distinctive brand in the Mainland China market with the backing of 民营.

From Shenzhen Bao’an the network covers major domestic cities plus regional international routes as demand allows. Departing from Shenzhen Bao’an gets you the best frequencies, timings and irregular-ops backup; from non-base cities expect more one-stops, so watch total journey time when booking.

Booking tips: fares float with live inventory — 2–6 weeks out (2–4 months long-haul) is usually the trough, and member pricing can undercut platforms. Join the loyalty program if you fly the brand often. Paid upgrade windows open around check-in at prices well below purchase-time premiums, and pre-bought extra baggage saves 30%+ versus airport rates.
