Juneyao Air does not fly nonstop to the United States. So the figures that matter most to a US traveler are the ones for a connection through Shanghai. The Juneyao Air baggage allowance splits into two systems.
Inside China it is a weight limit. Cross a border and it becomes a piece count instead.
Mixing up which system applies is the easiest way to get an unwelcome number at the counter. This page walks through both. It also covers what Juneyao charges when a bag misses either one.
Domestic China runs entirely on weight
Fly only within mainland China on Juneyao and the rule stays simple. Economy checks in 20 kg (44 lb) total. Business checks in 30 kg (66 lb) total, and either cabin can spread that weight across more than one bag, since it is a weight cap, not a bag count.
Each piece still needs to fit inside 100 by 60 by 40 centimeters, roughly 39 by 24 by 16 inches. No single piece may exceed 50 kg on its own. That linear limit is generous next to what most US carriers allow for a checked bag.
Cross a border and the Juneyao Air baggage allowance switches to pieces
Add an international leg and checked baggage moves from weight to a piece system. The details then depend on the region. Business class gets two pieces worldwide, up to 32 kg (about 70 lb) each, with a combined length, width and height cap of 158 cm, around 62 inches, per bag.
Economy gets one piece at up to 23 kg, about 50 lb, on most routes. That covers Southeast Asia, Russia and Europe. Flights to Japan, South Korea, Singapore and Australia are the exception, since economy gets two pieces there instead of one.
That regional split is the part of the Juneyao Air baggage allowance that catches travelers out. It is easy to assume one number covers every route. Check the exact city pair before you count on a second free bag.
Carry-on stays a weight limit no matter the route
Cabin baggage never switches to a piece system the way checked bags do. The same limits apply worldwide. That means one bag up to 8 kg in economy, or two bags up to 5 kg each in business, on domestic and international Juneyao flights alike.
The box itself is 55 by 40 by 20 centimeters, about 22 by 16 by 8 inches. International, Hong Kong, Macao and Taiwan routes add one more rule: the three dimensions combined cannot exceed 115 cm, about 46 inches. The standard box already meets that exactly.

What an extra or oversize bag costs
On most international routes, a piece beyond the free allowance runs 1000 RMB. A bag weighing 24 to 32 kg adds another 1000 RMB. That climbs to 2000 RMB for a bag between 32 and 45 kg.
An oversize bag, one measuring 159 to 203 cm combined, adds a further 1000 RMB on top of any weight charge. Europe and Australia routes price it differently. Overweight and oversize fees drop to 600 RMB each there, but a second extra piece jumps to 1200 RMB.
Juneyao’s own checked baggage page lists both fee tables in full, region by region. Domestic overweight fees work differently again. They are priced at 1.5 percent of the day’s highest fare for a one way economy ticket, per kilogram, so the dollar amount moves with the route.
Our baggage cost tool is a faster way to estimate what an overage will run than doing that math at the counter.
What travelers actually run into
Community discussion of Juneyao is thin next to what exists for the big US carriers. Two points still repeat. Travelers confirm the domestic allowance really is a weight limit, not a per bag count, which matches what Juneyao states on its own site.
Juneyao’s carry-on page names no separate personal item, unlike most US airlines. Travelers report that crews routinely let a small backpack ride under the seat in addition to the listed carry-on. Treat that as common practice at the gate, not a written entitlement you can insist on.
Lithium batteries and power banks are barred from checked bags entirely under Juneyao’s own rules. That lines up with the general rule on batteries in checked baggage. Pack those in the cabin bag every time.
How Juneyao compares to its Chinese peers
The weight then pieces split is not unique to Juneyao. China Eastern’s baggage allowance and China Southern’s baggage rules follow a similar pattern. So does Air China on its own routes.
What sets Juneyao apart for a US reader is simpler: there is no direct US route at all. The practical question is usually which partner or connecting carrier handles the leg into or out of the country, and whose allowance governs the through fare.
The bottom line
The Juneyao Air baggage allowance rewards travelers who check which system applies before they pack. A domestic Chinese leg is forgiving on bag count as long as the total weight fits. Any international leg reverts to a strict piece count that differs by region.
