never used my avios want to go to Vancouver in August Sept this year and use avios to book business return leg
So I have approx 220 000 avios I live in Ireland but can easily get to london if I look up air lingus site they want €2 200 per person to fly Vancouver via London. Economy is much more reasonable 405€. If I choose Economy what's the chance I can use avios to upgrade to business?
If I choose BA Vancouver to london business is 110 000 points per person 1 way which seems expensive.
