Checking in a bag on Ryanair - which this summer costs anything from UK Pound 25 to UK Pound 160 for a one-way flight - could soar still higher. Read

In May, this year, Air India lowered the free baggage allowance from 20 to 15 kgs on the domestic sector and start charging a flat rate of about Rs 200-250 per kilo on excess baggage.

This follows a Directorate General of Civil Aviation (DGCA) circular last week allowing the airlines to charge fees for 'unbundled services' like check-in baggage, preferential seats, meals, snacks or drink (barring drinking water) and sports and musical instruments on their domestic flights.

So far, there is no charge for checked-in luggage within weight limits, but given Ryanair's success story in increasingly competitive skies, it may only be a matter of time before Indian carriers adopt it.
