I have made reservations on this airlines without finding any information about their reputation. I will be flying them from London to Lisbon, Porto to Lisbon, and Lisbon to London the second week of June. I should have posted this request for information long ago. I leave in 4 days (June 3) flying from Seattle to London on Delta. I will also post this question on the Portugal web page but though it might get seen by more folks posting it here. Thanks for any info.
Here you go...although for such short flights, why worry at all? It's an average 3-star airline as judged by Skytrax. I assume the price will offset any inconvenience if plane is late.
I posted a reply on your other post. We took them last May- got where we needed to go on time with all our belongings.
