Spirit Airlines Using 734?

[FutureA320Pilot]

I noticed on Flight Aware that NK substituted their usual A320 on flight 180 between FLL-LGA with a 734. Anyone know why, and who they chartered this aircraft from?

FlightAware is screwy sometimes with the aircraft types. I see they have it as a 734 again today, and a 752 (!) for tomorrow. And they are always messing up the WN types, at least there, it's still a 737, just the wrong model, and that could be that they are getting bad info from Southwest. Never heard of them using an aircraft type that the airline doesn't fly, though.

Yes, as a matter of fact they're using a B734 leased from Xtra Airways N772AS for the next two months for the summer season. They also have leased before a B757 from Omni Air, both for the FLL-LGA route.

What exactly is the reason for this? Is there an aircraft currently undergoing maintenance?
