LY arbitrarily cancels flights, shifts flights by half or full day at short notice. Some of sold LY flights are phantom.
The company does not succeed to maintain a working call centre or any other communication channels - there are reports of waiting times of a few hours, and calls returned weeks after an initial request to resolve an urgent issue.
Website is limited in its functionality, and most things - including resolving the cancellations - would require calling them.

I would stick with BA, which with all its problems is still on another level when handling IRROPS.
