Baggage, changes and fare conditions

Allowances and fees differ by fare brand, route and booking channel, and carriers revise them often. Rather than print a number that may be wrong on the day you fly, here is what actually varies with Blue Islands and what to confirm before you pay.

Cabin baggageFull-service carriers normally include a cabin bag plus a personal item. Weight limits are enforced more strictly on narrow-body and regional aircraft.
Checked baggageOften included, by piece or by weight depending on the route. Long-haul allowances are usually more generous than short-haul.
Seat selectionAdvance selection is typically chargeable; free assignment at check-in is the fallback. Extra-legroom and exit rows carry a premium.
ChangesWhether a change is permitted, and the fee plus any fare difference, is set by your fare brand rather than by the airline as a whole.
Cancellation and refundsRefundability is a fare-brand property. Even on non-refundable fares, government taxes and some charges are usually reclaimable.
Name changesRules vary widely - some carriers permit a correction for a fee, others require a new booking. Check spelling against your passport at the time of booking.
Infants and childrenUnder-twos usually travel on a lap for a percentage of the adult fare; a seat requires a child fare and an approved restraint.
PetsIn-cabin carriage, hold carriage and breed restrictions differ per carrier and per destination, and some routes prohibit animals entirely.
Special assistanceRequest at least 48 hours ahead. Assistance is a legal entitlement in the EU, UK and US, but it must be booked to be guaranteed.

Where to confirm: the binding text is Blue Islands’ own conditions of carriage and the fare rules shown at checkout. If your ticket is a codeshare, the operating carrier’s baggage rules normally apply to the whole journey.
