Every Friday CTV Consumer Reporter Lynda Steele dips into the CTV mailbag and answers a handful of viewer questions.

David asks: Why does TransLink charge an extra $5 for tickets purchased at the Vancouver airport station?

TransLink said the premium airport fee was brought in to help bridge the funding gap when the Canada Line was built before last year's Olympic Winter Games.

The funding from the federal and provincial government and the Vancouver Airport Authority wasn't enough to cover the project's $2-billion cost.

Every three years there is a general review, so those fares are subject to change, but TransLink said it's expected to be 30 years before the Canada Line is paid off so it's not likely you'll see a decrease in that fare anytime soon.

You can get around paying the extra airport fee by using FareSaver tickets or a monthly pass, which are both exempt from the fee. So if you buy those tickets in advance you can avoid the cost of the added fare.

On the heels of our story about appliance recycling, Cathy asks: Where can you recycle old batteries?

Millions of batteries get thrown out every year. In addition to being a waste, it's also a hazard because those old batteries can leach dangerous chemicals into the soil.

But there are more than 1,200 collection sites in B.C.'s Call2Recycle program, which collect all household batteries and cell phones for recycling.

There are also lots of retail stores where you can drop them off in person, including most London drugs stores, Home Depot and Ikea.

So far this year Call2Recycle has saved more than 700,000 batteries from the landfill.

You can just type in your postal code on its website to find the recycling depots closest to where you live or work.

Finally an update to a story we brought you last week about Greyhound's so-called $18 "gift ticket fee."

The bus line charges the fee when you buy a ticket for someone else. Greyhound claims the fee is to cover handling costs but passengers are fighting back, saying the fee often hits low income customers the hardest who are trying to help out a relative or friend who can't afford a bus ticket.

An online petition has been launched demanding greyhound eliminate the so-called "price gouging fee."

Over 250 people have already signed up.
