britishairways.com speed test — 20 Oct 2026
Measured from the wfix.shop server on 20 October 2026 at 13:52 UTC. Grade A (98/100), with the screenshots, the timings and the fixes that matter.
Where the first byte went
- DNS lookup 49 ms 18%
- TCP connect 56 ms 21%
- Server wait 163 ms 61%
Measured on the connection that fetched the HTML. Every other request on the page waits for the end of this bar before it can start.
How this page compares
Every report published here is in this comparison, so it is a reference population of pages tested from one server - not a benchmark of the whole web.
What these numbers mean
- The first byte arrived in 268 ms. That is workable, and the cheapest win left is caching or a warmer connection.
- The page transfers 4.6 KB over 1 request(s), which is lean.
- The HTML itself arrives gzip-compressed.
- It runs over HTTP/3, so the assets share a connection instead of opening one each.
- The largest element painted at 476 ms, inside the 2.5 s Google calls good.
Fix first: Strict-Transport-Security - Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.
Read on one shared server, not a visitor's phone: use it to compare pages against each other, not as a promise about every connection. We fix what these tests find.

What the page looks like
Loaded in headless Chromium on this server. Click an image to open it full size.
Browser render
The same URL loaded in a real browser, so these are the readings curl cannot produce. The grade above is still built from the server measurements.
Top issues
Strict-Transport-Security
low impactHSTS is not set, so the first visit on a hostile network can still be downgraded to HTTP.
Fix: Send Strict-Transport-Security with a max-age of at least six months. Add includeSubDomains once every subdomain is HTTPS.
