Find confirmed upgrade and award space before you book

No credit card required

Updated .

Upgrades are valuable. Using them shouldn't be this hard.

You earned the status. You're holding systemwide upgrades, Global Upgrade Certificates, or Alaska certs. But finding flights with confirmed space means searching carrier by carrier, route by route, date by date, and availability opens and closes without warning. By the time you check, it's gone.

Time-consuming searches

Upgrade inventory is per-segment, per-carrier. A connecting trip means separate searches for every leg.

No visibility

Upgrade space changes between checks. Without monitoring, you only see the moment you look.

Wasted upgrades

Systemwide upgrades expire. Certificates go unused, and your most valuable benefits go to waste.

How 2LNR works

Three steps from your inbox to a confirmed seat up front.

1

Bring your trips

Connect Gmail or Outlook, or forward a confirmation, and your trip board builds itself. Or add a flight by hand.

2

We find the space

2LNR monitors confirmed upgrade availability on American, Delta & Alaska and award space across more than 20 airlines, segment by segment.

3

Act the moment it opens

See exact seat counts before you book, and get an alert the second availability changes.

The method in one page: confirm the space, then book.

Built for how you travel

Holding SWUs or GUCs?

Into points and miles?

Just want a better seat?

Seat monitoring watches your flight and pings you when a better seat opens, or warns you when an aircraft swap moves yours.
