As airline fees come and rarely go, I ponder what charge will be accessed next? It seems nothing is sacred in the realm of fees, and the included-in-price perk of a seat assignment may be the next casualty of the complimentary. 

This week British Airways announced it would begin charging a fee for travelers wishing to reserve a seat at time of booking. Up until October 7, travelers will be able to (as in the past) reserve seats 24 hours prior to departure without a fee associated. After that date, pre-reserved one-way seats will run from $16 for economy flights within Europe to $96 for business class long-haul seating to $80 for an exit row on a long-haul flight.

What's next? If I was a betting man, I'd have to say a rental charge for the the seatback tray. 

PS: My apologies for the title, as it may have you humming, How much is that doggy in the window?
