essexyid,

It's only an odd flight where an aircraft has needed to be substituted at the last moment due to a technical problem. The vast majority of flights run as scheduled so I wouldn't sorry. It's a case of delaying the flight for a few hours or upwards of a day, depending on the nature of the problem and therefore delaying passengers, and subsequant passengers resulting in losing part of the holiday, or getting you away with only a minor delay but on a short haul configured aircraft. Having been subject to a 52 hour delay a few years ago (not with Thomson Airways), I know what I'd choose! Your flights are operated by a former First Choice Boeing 767-300/ER. You'll find extensive aircraft information on our What Aircraft? guide (link below). There isn't a specific registration allocated to your flight, the fleet is rotated weekly so I won't know until the day before. It makes little difference anyway as all but 1 are the same inside.
