I bid to fly business class and won. It had great food and felt luxurious, but I wouldn't pay full price.

• I flew from London to Helsinki and snagged a bargain upgrade to business class for £75.
• I got priority boarding, a meal, and access to the business lounge (though I didn't end up going).
• Here's what it was like and how I made the most of Lufthansa's upgrade offer.

I live in the UK but have family in Finland, so I tend to travel back and forth a few times a year. I most recently visited in June. I was booked to travel, as usual, in economy class from London to Helsinki, with a short layover in Munich.

Once I booked my trip, I received an email from Lufthansa with the usual details. But having seen some posts on social media about people "bidding" for upgrades, I decided to look into it. A quick online search yielded the right section on the German carrier's website.
