Yes, HYG has some HY airliners but that doesn't make the actual issuers available for any of these facilities. That's the point that I was making.
Several IG airlines could have issued over the past few weeks but haven't for a reason. We have had a flood of IG new issuance and not a single airline or adjacent industry. CCL which basically has the same problems as airlines right now (gov basically making business illegal) was able to raise quite a bit of money. Difference is, they know that they aren't going to get bailed out.
And as of today my initial comment is out of date since DAL got downgraded.
