Spokespeople for the companies say that the new charges will help them keep their flight fares competitive. The move was made after U.S. airline JetBlue Airways Corp. increased their own check-in baggage fees.

Both airlines have applied these increases to the lowest fare classes. Baggage fees will remain static for all other types of tickets.
