Abacus International Pte. Ltd.
This listing combines Singapore-based travel-distribution company Abacus International with BH Air, a Bulgarian leisure airline; the supplied identifiers do not describe a single carrier.
About Abacus International Pte. Ltd.
The supplied record combines two different businesses. Abacus International Pte. Ltd. was established in Singapore in 1988 as an Asia-Pacific travel-distribution company, not as an operating airline. BH Air, the legal name and website supplied here, is a Bulgarian leisure carrier founded in 2001 and associated with tour-operator flying. ICAO designator BGH also identifies BH Air, while IATA code 1B has historically been used for Abacus distribution services rather than BH Air flights. Travellers should therefore verify which company a booking record actually references.
BH Air is based in Sofia, Bulgaria, and operates principally from Bulgarian airports, including Sofia, Burgas and Varna. Its flying is oriented toward charter and seasonal leisure traffic, connecting holiday markets in Bulgaria with source markets elsewhere in Europe and, when contracted, destinations farther afield. Unlike a large scheduled network airline, its timetable can change substantially between seasons and according to tour-operator agreements, so a permanent destination count or stable year-round route map may be misleading.
The airline has operated Airbus A320-family aircraft, a widely used narrow-body type suited to short- and medium-haul leisure services. Aircraft are generally configured around high-capacity economy seating, reflecting the charter-focused business model rather than a conventional multicabin network-airline product. Service inclusions can depend on the tour operator, fare or holiday package through which travel is purchased. Passengers should check their booking confirmation for seat selection, meals, baggage and other included services.
BH Air is not a member of Star Alliance, SkyTeam or Oneworld, and no dedicated BH Air frequent-flyer programme is reliably identified. Abacus International likewise functioned as a reservation and distribution provider rather than an airline loyalty scheme. Travellers cannot assume that alliance status benefits, mileage earning, lounge access or reciprocal elite privileges apply merely because another airline or travel agency appears on the same itinerary. Any benefits should be confirmed with the ticketing carrier.
A practical strength of BH Air is its focus on direct leisure flying, which can provide convenient links aligned with package-holiday demand. The corresponding challenge is that schedules, sales channels and onboard inclusions are less standardized than those of major scheduled airlines. Some flights may be sold primarily through tour operators rather than directly to individual passengers. Because this directory input merges Abacus and BH Air data, travellers should confirm the operating carrier, flight number, departure airport and baggage terms before payment and again before travel.

FAQ
Abacus International Pte. Ltd. — frequently asked questions
Quick answers to the details travellers usually check first, from codes and locations to the practical basics that help with planning.
8 common questions
- Abacus International has no routes. BH Air's charter programme changes, so there is no reliably fixed longest route that applies across seasons.
- Abacus International does not fly aircraft or serve destinations as an operating airline. BH Air operates seasonal and charter services from Bulgaria, with its route programme varying by season and tour-operator contract.
- There are no Abacus-operated flights. For BH Air services, Sofia, Burgas and Varna are important Bulgarian departure airports, although the active programme depends on the season.
- Abacus International does not sell flights as an operating carrier. For BH Air leisure services, prices depend heavily on season, package availability and tour-operator inventory; comparing flexible dates outside peak holiday periods may reveal lower fares.
- Originfacts compares live fares from hundreds of airlines and travel agencies via its partner Travelpayouts and never adds a fee. The booking result should be checked carefully to identify the actual operating airline, especially because Abacus itself is not an air carrier.
- No airline destination count applies to Abacus International because it is a travel-distribution business. BH Air does not maintain a dependable fixed count for its changing charter and seasonal network.
- Abacus International was a Singapore-based travel-distribution company and did not operate an airline hub. BH Air, the carrier identified by the supplied legal name, is based primarily at Sofia Airport and also operates leisure flying from Burgas and Varna.
- Abacus International has no carry-on policy because it is not an operating airline. If the flight is operated by BH Air, consult the ticket or tour operator for the applicable cabin-baggage size and weight limits.
