Best and worst seats

Best seats

  • Rows 1–7 and 9–11, seats A and K · Air Canada Signature Class

    Window seat in Air Canada Signature Class, angled toward the window with its own aisle access: the most private seat in the cabin.

  • Row 12, seats A, C, H and K · Premium Economy

    First row of Premium Economy: nobody reclines into you, though the bulkhead in front means no under-seat bag space.

  • Row 12, seats D, E, F and G · Premium Economy

    First row of Premium Economy: nobody reclines into you, though the bulkhead in front means no under-seat bag space and the bassinet position may seat a baby here.

  • Rows 31 and 51, seats A, B, C, H, J and K · Economy Class

    Exit row on Air Canada's table: extra legroom. You must be willing and able to help in an emergency, and bags go overhead for take-off and landing.

  • Rows 61–63, seats A, C, H and K · Economy Class

    One of two seats together where the cabin narrows: no third seat to share, good for couples. The map doesn't letter these seats; the letters here are likely.

Trade-offs

  • Row 1, seats D and G · Air Canada Signature Class

    Bulkhead row, so nobody reclines into you

  • Rows 2–6 and 9–11, seats D and G · Air Canada Signature Class

    Centre pair angled toward each other: good for a couple, less private for someone flying alone.

  • Row 8, seats D and G · Air Canada Signature Class

    Next to a galley, with light and noise during service

  • Row 18, seats A, B, C, D, E, F, G, H, J and K · Economy Class

    Bulkhead row, so nobody reclines into you

  • Row 23, seats A and K · Economy Class

    Next to a lavatory, with queues, noise and flushing

  • Rows 30 and 50, seats D, E, F and G · Economy Class

    Bulkhead row, so nobody reclines into you

Seats to avoid

  • Row 23, seats B, C, D, E, F, G, H and J · Economy Class

    Next to a lavatory, with queues, noise and flushing

  • Row 43, seats A, B and C · Economy Class

    Next to a lavatory, with queues, noise and flushing

  • Row 43, seats D, E, F and G · Economy Class

    Next to a galley, with light and noise during service

  • Row 64, seats A, C, D, E, F, G, H and K · Economy Class

    Last row of Economy Class, with lavatories or a galley behind it: recline is likely limited and there is traffic and noise.
