Feb 15 (Reuters) - Finnair (FIA1S.HE) reported a second straight quarterly operating profit on Wednesday as the impact of COVID-19 lockdowns eases on its key Asian business, and said it looked forward to potentially "huge" demand from the Chinese market. In the fourth quarter, 31.2% of its passenger revenue came from Asian traffic, versus 41.1% in the same period in 2019. Finnair said it expects to significantly increase its 2023 revenue compared with the previous year, but not yet to reach pre-pandemic levels. Its comparable operating profit reached 17.9 million euros ($19.2 million) in the fourth quarter, against a loss of 65.2 million a year earlier. Finnair shares were up 1.1% at 0.5345 euros by 1506 GMT, after rising as high as 0.5520, their highest since February 2022.
