For flights from Boston (BOS) to Lyon (LYS), cabin baggage on the long-haul Condor flight consists of one carry‑on bag up to 55 × 40 × 20 cm plus one small personal item 40 × 30 × 10 cm; the combined cabin baggage weight limit is 8 kg in Economy Class, 10 kg in Premium Economy Class, and 16 kg in Business class, with one Business Class cabin bag limited to 10 kg. Economy Class fares that include checked baggage provide one checked bag up to 23 kg, Premium Economy includes one checked bag up to 32 kg, and Business Class includes two checked bags up to 32 kg each on US–Europe journeys. Each checked bag must remain at or below 32 kg and within a total linear dimension of 158 cm (length + width + height); heavier bags cannot be accepted.

On Condor flights from Boston (BOS) to Lyon (LYS), small dogs and cats can travel in the cabin on the long-haul and connecting flights if they meet the size and weight limits and all entry rules for France and the European Union. For pets in the cabin, a watertight, bite‑proof carrier of up to 55 × 40 × 20 cm is required, with a maximum weight of 8 kg including the animal, and the carrier must stay closed under the seat in front for the entire flight; pets are not permitted in Business Class on long-haul flights or in exit and bulkhead rows. Animals that do not fit in the cabin carrier would normally travel in the aircraft hold in a suitable, well‑ventilated transport crate for air travel, but transport of animals in the hold is not permitted on itineraries with a connection, so the Boston (BOS)–Lyon (LYS) journey only allows pets in the cabin. An EU pet passport with proof of rabies vaccination is required for dogs and cats entering the European Union, and certain breeds such as fighting dogs and snub‑nosed dogs and cats are excluded from transport. Assistance dogs are accepted subject to health, training, and documentation requirements and must be arranged in advance.
