    HTTP headers are a curious beast. At the surface level they look roughly
    like a name-value set, but in practice they have many variations that
    make them tricky:

Google's server is providing an incorrect pseudo-header field. Their response contains the pseudo-header field ':status' with the value '302 Found', in violation of the draft. The relevant section is Section 8.1.2.4 of the h2-14 draft, which reads:

A single ":status" header field is defined that carries the HTTP status code field (see [RFC7231], Section 6). This header field MUST be included in all responses, otherwise the response is malformed (Section 8.1.2.6).

HTTP/2 does not define a way to carry the version or reason phrase that is included in an HTTP/1.1 status line.

A Thankyou To Google

Dear Google,

I'd just like to thank you for disabusing me of the idea that JSON is under some requirement of well-formedness. I'd been labouring under the tyrannical misapprehension that some standards body had written down how JSON was supposed to work and that if I wanted to claim I was using JSON I would have to comply with that specification.

However, I today received a bug report indicating that a project to which I contribute was unable to make HTTP requests your Google Flights website could understand. I found this perplexing, but my eyes were opened when I saw your HTTP request. In particular, I enjoyed your freeform and inclusive definition of JSON. Allow me to show you what you've called JSON by showing you my SPDY request:
