I want to buy a ticket from Beijing to Vancouver. I have a few questions to write down in the details.

1. Is it reliable to book tickets with China Air China APP? This is the official APP, and I have been worried about Tuniu Ctrip and so on.

The APP of Air China official website is more reliable.

Second, the plane ticket I bought said 1PC. Can I only check one piece of luggage or can I check several pieces at an extra charge?

Two pieces of free luggage checked by American Airlines.

3. What is the size and weight limit of checked luggage for international flights to Vancouver? At present, there are three questions, please let me know, thank you.

The weight limit of each piece of luggage is 23kg (50lbs), and the sum of three sides of each piece of luggage shall not exceed158cm (62in); ?
