What's keeping flyhigh-booking.com from an A

Mail servers without IPv6
mx.stackmail.com has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
Nameservers without IPv6
ns1.beak.host, ns4.beak.host, ns3.beak.host, ns2.beak.host all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
