2LNR vs SeatSpy: two calendars, different coverage

A whole year of a route in one search

Checking reward seats date by date on an airline's site is slow. SeatSpy puts almost a whole year of a route on one screen, every cabin included, so you see the open dates without hunting for them. 2LNR took the same approach to upgrade space.

Depth on Avios and Virgin Points specifically

Being built around British Airways and Virgin Atlantic first means the details are right for those programs: the cabins, the taxes-and-fees reality, and the way availability actually behaves on those routes. The list has grown to nine airlines, and a tool that covers nine properly beats a tool that covers forty vaguely, if those nine are your programs.

It's still being developed

SeatSpy was still adding Avios features in February 2026, when Head for Points ran a sponsored post on its new airport, flight-time and single-flight filters, so this is a maintained product rather than a dormant one. That's worth saying on a site that also publishes a page about a seat tool that shut down.

Upgrade certificates, not just reward seats

A reward seat and an upgrade are different inventory. An American systemwide upgrade clears against C-class space (A class for Flagship First), Delta Global and Regional Upgrade Certificates clear against their own buckets, and Alaska certificates clear against U-class first class. No reward-seat calendar shows the American or Delta space. 2LNR tracks all three per flight and date.

The American workflow is in the step-by-step SWU search guide.

A wider award map, US carriers included

2LNR's award matrix covers more than 20 airlines rather than SeatSpy's nine, American, Delta, Alaska and JetBlue among them, which matters if your redemptions move between programs or start in the United States. The trade runs both ways: a broad map is less specialized than a tool built around Avios and Virgin Points, so pick by where your points actually live.

One alert engine over both kinds of space

Pro gives you unlimited alert rules across award and upgrade space at once, by email, SMS, in-app and push, with no per-tier cap on how many routes you watch. Trips import automatically from Gmail or Outlook, so the routes you fly fill themselves in instead of being typed one at a time.

How the rules work is in real-time alerts.

Use SeatSpy if you redeem on BA or Virgin Atlantic

If your points are Avios or Virgin Points, your redemptions run out of the UK, and the question is which day next spring has two Club World seats, SeatSpy does that job well and prices it modestly. Adding a second tool on top of it would be paying twice for the same answer.

Use 2LNR if you hold US-carrier status or certificates

If you fly American, Delta or Alaska, hold upgrade certificates, and want award space across a wider set of programs in the same calendar, that's 2LNR. The American systemwide and Delta certificate space is the part no reward-seat tool can show you, whatever its coverage list looks like.
