Xi’an is quite an interesting airport with a lot of variety, particularly a lot of one or twice a day flights from carriers such as Hebei and Urumqi, as well as assorted operations from the Hainan group carriers: Air Changan are based, Tianjin have 8-9 different E190s a day, and both Tianjin and Capital operate their Airbus single aisles: GX Airlines and Lucky Air also visit. Hainan themselves have a few 737 flights and 3-4 A330s a day.
When planning this trip I made extensive use of the advice offered on this website: https://globalspotting.wixsite.com/global-spotting/china-. At Xi’an the Regal Airport hotel (same company as HKG) is linked directly to terminal 3 and terminal 3 is linked to Terminal 2 used by Air China and Hainan group). Terminal 1 looks like a disused prison and handles the occasional Spring flight. The whole airport layout is quite odd, as it’s effectively locked in by roads and taxiways, a little bit like Luton except bigger. There are parallel runways at Xi’an, low numbered rooms in the Regal will look at either of these (odd numbers facing the northern runway/Hainan side, and even numbers facing the southern runway/China Eastern side). Higher even numbers face out towards the approach to the 05s, however the threshold of 05L cannot be seen, and there is nowhere within the hotel to be able to see this from. However the end or 05R can be seen, as well as some remote parking.
The presence of eleven stored ex-Hainan/Grand China Express Dornier 328 Jets was one of the attractions of Xi’an ….. and my attempts to see them were thwarted. I started on foot, and kept walking around the inside of the airfield until I met a building site, and the only way round was on the motorway to the airport. I suspect the Chinese would just have kept going but my interest in walking on motorway flyovers was non-existent. I then tried a succession of taxis outside the hotel with my best Bing Translate (Google is blocked in China) description of where I wanted to go, and just got variations of ‘no’ as an answer. My impression was they didn’t want to go where I wanted to go.
When I left Xi’an I thankfully had a window seat on the correct side to see the storage area, as well as eleven DoJets there were single examples of a Tainjin Em145 (known) and Em190 (not known) as well as four Capital A319/320 (not known, but I haven’t attempted to work them out yet) as well as Fuzhou 737Max8. I can send a photo if anyone wants one. In addition on arrival I saw Capital A319 B-6108 all taped & bagged up, and there are two Hainan DoJets and two Em145s in a compound overlooked by the Regal Hotel.
