Greater Bay Airlines, Hong Kong’s young low-cost regional carrier, sells five branded fares and the cheapest one — GO GO Promo — gets you a carry-on and nothing in the hold. You bring 7 kg of cabin baggage (max 115 cm total) plus a small personal item, and any checked bag is a paid add-on. The next fare up, plain GO GO, includes 1 piece up to 20 kg in the hold, which is the rung most deal-hunters actually want.
Above that, Value GO gives 2 pieces / 30 kg total, and Flex GO and Premium GO both bundle 2 pieces / 40 kg total. The good news: Greater Bay flies short and medium-haul only — Tokyo, Osaka, Bangkok, Taipei, Manila, Seoul and mainland China — so there is no region split on the cheapest fare. A GO GO Promo ticket strips the checked bag whether you’re flying 50 minutes to Taipei or 5 hours to Bangkok.

What you actually get on a cheap fare
On a rock-bottom Greater Bay deal fare (GO GO Promo) you get a seat, a 7 kg cabin bag and a personal item — and that’s it. There is no hold bag, no seat selection, and limited changes. If the headline price looks like a steal, assume you’ll be adding a bag: budget around HK$380 (roughly US$48) per 20 kg piece if you prepay online, and far more (HK$780) if you leave it to the airport counter.
The smart move is usually to compare the GO GO Promo price plus a prepaid bag against booking plain GO GO outright, which already includes 20 kg — on many dates the bundled fare costs less than promo-plus-bag. Whatever you do, add the bag before you fly: the airport rate is more than double the online rate, and prepaid bags are non-refundable.
Oversize, sports & special items
Checked pieces over 158 cm but under 203 cm are accepted as oversized with excess charges and need pre-approval; anything over 203 cm or 32 kg is refused outright. Sports equipment and musical instruments must be properly packed — instruments can travel in the cabin if they fit the overhead bin, otherwise they’re treated as excess baggage and need 72 hours’ advance notice. Smart bags with non-removable lithium batteries are banned; removable batteries must come into the cabin.
From 28 March 2026, Greater Bay limits each passenger to a maximum of two lithium-battery power banks onboard, with restrictions on where they can be stowed and used — in line with the wider Hong Kong / regional crackdown on power banks.
