Carry-On Only for Sofia: Airline Bags and Arrival Planning

For a Sofia trip, choose the bag allowance before building the packing list. A free underseat item and a paid overhead bag are different products. A backpack described as “40 litres” has no guaranteed fit: measure its packed exterior and weigh it.

Airline quick reference

Use the Bulgaria Air checker for one bag’s dimensions and weight. It does not add the main bag and personal item together: weigh both separately and check the 12 kg combined limit yourself. On partner-operated segments, including the published airBaltic Riga–Sofia exception, use the actual operator’s conditions.

For low-cost flights, check the exact baggage product in the booking. A paid checked bag does not automatically include an overhead bag. Noncompliant baggage can attract charges; do not rely on free gate-checking. See the Wizz Air rules and Ryanair rules before paying for an add-on.

Pack for the activities you will actually do

For city days, start with comfortable shoes, layers matched to the forecast and a compact rain layer. If you plan a mountain outing, check the route, weather, daylight and return transport separately. Do not assume a cable car is operating or that every trail is suitable for your experience.

Keep travel documents and necessary medication accessible. A daypack packed inside the main bag can be useful after arrival; carrying it separately at boarding still counts under the airline’s item allowance. Leave room for anything you expect to bring home. Compressing clothing changes volume, not weight.

Arrival transport and spending money

Sofia Airport is served by metro line M 4, with the station beside Terminal 2. Check your terminal and the operator’s current service information before arrival, especially for a late flight. Allow for the walk, baggage collection and any terminal transfer; a city-centre journey time is not the whole airport-to-hotel trip.

Bulgaria introduced the euro on 1 January 2026. Budget current expenses in euros and check displayed prices. This guide does not promise restaurant, taxi or accommodation prices.

Before returning to the airport, repack and measure the bag again. Souvenirs, an extra coat or a separate shopping bag can change the item count or dimensions even when the outbound bag fitted.
